<h2 id="h-what-is-an-api-sandbox"><span id="What_is_an_API_Sandbox">What is an API Sandbox?</span></h2>



<p>An API sandbox is a service that simulates the behavior of a production API. While the distinction between sandboxes and mock APIs may vary, sandboxes are typically intended for external developers. It provides a valuable platform for developers to test APIs without any risks or expenses, making them a vital part of a DX-oriented API strategy.</p>



<p>The primary purpose of an API (Application Programming Interfaces) sandbox is to enable developers to understand how to interact with an API, test their integration code, and evaluate the API&#8217;s capabilities before deploying it in a live application. It provides a safe space to experiment, troubleshoot, and validate API requests and responses.</p>



<h2 id="h-features-of-an-api-sandbox"><span id="Features_of_an_API_Sandbox">Features of an API Sandbox</span></h2>



<p>An API sandbox typically offers the following features,</p>



<h3 id="h-1-easily-accessible-to-any-api-client"><span id="1_Easily_Accessible_to_Any_API_Client">1. Easily Accessible to Any API Client</span></h3>



<p>The API Sandbox is a testing environment that enables developers to<a href="https://testsigma.com/guides/api-testing/" target="_blank" rel="noreferrer noopener"> test APIs</a> without real-time consequences. It&#8217;s open to all types of API clients, including web, mobile, and desktop applications.</p>



<h3 id="h-2-high-versatility"><span id="2_High_Versatility">2. High Versatility</span></h3>



<p>The API sandbox is versatile and supports various API types, such as RESTful, SOAP-based, and GraphQL. This flexibility makes it an ideal tool for developers working with different types of APIs.</p>



<h3 id="h-3-simulated-environment"><span id="3_Simulated_Environment">3. Simulated Environment</span></h3>



<p>The API sandbox offers developers a simulated environment that imitates a real API. It enables them to safely test their API calls and responses within a controlled setting.</p>



<h3 id="h-4-customizable"><span id="4_Customizable">4. Customizable</span></h3>



<p>The API sandbox is highly customizable, giving developers the flexibility to adjust it according to their requirements. They can modify and test various aspects of the API, such as endpoints, headers, parameters, and more.</p>



<h2 id="h-7-best-practices-for-sandbox-api"><span id="7_Best_Practices_for_Sandbox_API">7 Best Practices for Sandbox API</span></h2>



<p>When working with a sandbox API, it&#8217;s crucial to follow the below best practices to ensure a smooth and effective testing process. Here are seven best practices for working with a sandbox API,</p>



<h3 id="h-1-isolate-your-sandbox"><span id="1_Isolate_Your_Sandbox">1. Isolate Your Sandbox</span></h3>



<p>You should make sure that the sandbox remains isolated from the platform. A sandbox must allow the development team to simulate the API&#8217;s behavior, but it should not allow any direct interaction with the platform in a way a production API will.</p>



<p>That is why it is considered best to build your sandbox in an isolated environment from the ground up. Because when you’re not careful with the sandbox, it could affect the production systems, lead to billing confusion, or even expose real data.</p>



<h3 id="h-2-provide-free-access"><span id="2_Provide_Free_Access">2. Provide Free Access</span></h3>



<p>Developers should have free access to the sandbox. It&#8217;s important to offer this because the main advantage of using a sandbox is that it&#8217;s free. This is especially beneficial for potential developer customers who might otherwise have to go through a lengthy approval process to get permission to try even the most affordable trials.</p>



<p>Although hosting a sandbox does come with costs, it&#8217;s essential for customer acquisition and developer experience. If providing an unlimited sandbox is not feasible, you can provide developers with a limited number of free sandbox credits when they register. This will reduce the amount of usage but still allow them to test.</p>



<h3 id="h-3-recreate-production-behavior"><span id="3_Recreate_Production_Behavior">3. Recreate Production Behavior</span></h3>



<p>When creating a sandbox environment for developers, it is important to ensure that it closely mimics the behavior of the real production system. This similarity allows developers to test their integrations with confidence, knowing that the sandbox will behave the same as the actual production API. Without this assurance, developers would need to repeat their testing using the real API, which undermines the purpose of having a sandbox.</p>



<p>To achieve this, it is vital to align the sandbox with the production API&#8217;s features. For example, if the production API supports POST requests, the sandbox should also support POST requests. Similarly, the sandbox should also implement pagination if the production API includes pagination. It is likely that the sandbox will be based on an API specification, so it is important to identify any gaps or limitations in the specification and address them accordingly.</p>



<h3 id="h-4-remember-about-authorization"><span id="4_Remember_About_Authorization">4. Remember About Authorization</span></h3>



<p>Do not overlook the authentication or authorization methods used by your production API. It is often neglected but crucial for developers. Ensure that you include it in your sandbox environment, whether you utilize API keys or access tokens.</p>



<h3 id="h-5-account-for-gateways-or-proxies"><span id="5_Account_for_Gateways_or_Proxies">5. Account for Gateways or Proxies</span></h3>



<p>While building your sandbox, it is vital to consider the impact of any gateways or proxies. Although they are not part of the API itself, they can still significantly impact developers&#8217; integrations. A key example is rate limiting, often implemented at the gateway level and can greatly affect integration behavior.</p>



<p>You have the flexibility to manage and handle these issues. Some API owners apply the same rate limits to sandboxes as they do to production APIs. However, others, like Salesforce, increase sandbox limits to allow more comprehensive testing.</p>



<p>The most preferred approach is the one by Evernote. In this approach, rate limits for both production and sandbox APIs kick in after a specific number of calls per hour. However, sandbox users are only rate-limited for 15 seconds rather than the entire hour.</p>



<p>This approach allows developers to test and handle rate limit exceptions without waiting for the one-hour interval to end before resuming interactions with the API.</p>



<h3 id="h-6-review-sandbox-usage"><span id="6_Review_Sandbox_Usage">6. Review Sandbox Usage</span></h3>



<p>It&#8217;s a good idea to regularly review how your API sandbox is used. By checking the sandbox&#8217;s logs, you can identify any unexpected usage patterns and provide support for them. It&#8217;s also important to look for frequently occurring errors, particularly during the onboarding process, as fixing these common pain points can improve retention.</p>



<h3 id="h-7-consider-a-chaos-mock"><span id="7_Consider_A_Chaos_Mock">7. Consider A Chaos Mock</span></h3>



<p>In high-stake industries, it is recommended to develop a chaos mock along with the regular sandbox for mature API programs. The chaos mock, introduced by Microsoft architect Gareth Jones, is a form of API virtualization designed to incorporate various unpredictable behaviors.</p>



<p>Its purpose is to allow developers to test their code against a wide range of unpredictable API behaviors, ensuring that their integrations can withstand any situation.</p>



<h2 id="h-benefits-of-api-sandboxes"><span id="Benefits_of_API_Sandboxes">Benefits of API Sandboxes</span></h2>



<p>Some of its key benefits include,</p>



<ul><li>It reduces the costs and potential risks related to testing third-party APIs.</li><li>It allows simultaneous testing and development, which accelerates application development cycles and reduces the time to launch the product in the market.</li><li>Allows risk-free testing and experimentation</li><li>It saves money and time</li><li>It improves security</li><li>Helps mitigate risks and ensures stability</li><li>Cost-effective development and resource utilization</li><li>Faster development cycles</li></ul>



<p>Also, do not confuse between API sandbox and <a href="https://testsigma.com/blog/api-testing-basics/" target="_blank" rel="noreferrer noopener">API testing</a>. API sandbox provides a controlled environment for developers to interact with and test APIs, while API testing encompasses the broader process of evaluating the functionality, performance, security, and integration aspects of APIs.Also, you can <a href="https://testsigma.com/automated-api-testing" target="_blank" rel="noreferrer noopener">automate your API tests</a> using test automation platforms like Testsigma.

<h2 id="h-understanding-equivalence-partitioning"><span id="Understanding_Equivalence_Partitioning"><strong>Understanding Equivalence Partitioning</strong></span></h2>



<p>Equivalence partitioning is a <a href="https://testsigma.com/guides/black-box-testing/" target="_blank" rel="noreferrer noopener">black-box testing</a> technique that allows testers to group input data into sets or classes, making it possible to reduce the number of test cases while still achieving comprehensive coverage. This technique is particularly useful when dealing with a large range of input values. Let&#8217;s walk through an example to understand the concept and process of Equivalence Partitioning.</p>



<p><strong>Testing a Login Form</strong></p>



<p>Suppose we have a login form with a username field. To apply Equivalence Partitioning, we can divide the possible input values into equivalence classes based on their expected behavior.</p>



<p><strong>Equivalence Classes:</strong></p>



<p>1. Valid Usernames: Alphanumeric usernames with a length of 5 to 15 characters.</p>



<p>2. Invalid Usernames: Usernames containing special characters or exceeding the length limit.</p>



<p>3. Empty Usernames: Leaving the username field empty.</p>



<h2 id="h-step-by-step-process-of-equivalence-partitioning"><span id="Step-by-Step_Process_of_Equivalence_Partitioning"><strong>Step-by-Step Process of Equivalence Partitioning:</strong></span></h2>



<p>1<strong>. Identify the input field</strong>: Determine the input field to be tested, such as the username field in our example.</p>



<p>2. <strong>Define equivalence classes</strong>: Categorize the possible input values into distinct equivalence classes. Each class represents a set of inputs with similar behavior or characteristics.</p>



<p>3. <strong>Determine representative values</strong>: Select representative values from each equivalence class. These values should cover the boundary conditions and critical scenarios within each class.</p>



<p>4. <strong>Create test cases</strong>: Generate <a href="https://testsigma.com/guides/what-is-test-case/" target="_blank" rel="noreferrer noopener">test cases</a> that cover each equivalence class. For example, one test case would include a valid username, another would include an invalid username, and a third test case would cover an empty username.</p>



<p>5.<strong> Execute the test cases</strong>: Run the test cases using the defined equivalence classes to validate the behavior of the system. Observe and record the results for each test case.</p>



<p>By following this step-by-step process, testers can effectively apply Equivalence Partitioning to streamline test case design and achieve comprehensive test coverage while minimizing redundancy.</p>

<h2 id="h-frequently-asked-questions"><span id="Frequently_Asked_Questions"><strong>Frequently Asked Questions</strong></span></h2>



<h3 id="h-is-equivalence-partitioning-a-black-box-test"><span id="Is_Equivalence_Partitioning_a_black_box_test">Is Equivalence Partitioning a black box test?</span></h3>



<p>Yes, Equivalence Partitioning is a black-box testing technique. It focuses on testing the functionality of the software from an external perspective, without considering the internal structure or implementation details. Testers identify and categorize input values into equivalence classes based on their expected behavior, without knowledge of the internal workings of the system. This allows for comprehensive testing while maintaining independence from the internal code.</p>



<h3 id="how-many-test-cases-for-equivalence-partitioning"><span id="How_many_test_cases_for_equivalence_partitioning">How many test cases for equivalence partitioning?</span></h3>



<p>The number of test cases for equivalence partitioning depends on the number of identified equivalence classes. In general, for each equivalence class, at least one test case is needed to represent that class. So, the total number of test cases would be equal to the number of identified equivalence classes. However, it&#8217;s important to note that additional test cases might be required to cover specific boundary or edge cases within each equivalence class. Therefore, the exact number of test cases may vary based on the complexity of the system and the identified equivalence classes.</p>

<h2 id="h-what-do-you-mean-by-levels-of-testing"><span id="What_do_you_mean_by8221Levels_of_Testing8221"><strong>What do you mean by&#8221;Levels of Testing&#8221;?</strong></span></h2>



<p>Testing levels, also known as levels of testing, refer to the different phases or stages of testing software during its development cycle. The main idea behind this concept is that each level of testing targets specific aspects of the software&#8217;s functionality, which allows for better quality assurance and fewer potential defects.</p>



<p>The most common <a href="https://testsigma.com/blog/the-different-software-testing-types-explained/" target="_blank" rel="noreferrer noopener">types of testing</a> levels include &#8211; unit testing, integration testing, system testing, and acceptance testing. Unit tests focus on individual components, such as methods and functions, while integration tests check if these components work together properly. System tests verify that the entire system meets the functional requirements specified by stakeholders, while acceptance tests validate the software against their criteria for acceptable behavior.</p>



<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" src="https://testsigma.com/blog/wp-content/uploads/Levels-of-testing-1.png" alt="Levels of Testing" class="wp-image-31585" width="362" height="294"/></figure></div>



<h2 id="h-what-are-the-different-levels-of-testing"><span id="What_are_the_Different_Levels_of_Testing"><strong>What are the Different Levels of Testing?</strong></span></h2>



<p>Software must go through different testing stages before it can be considered bug-free and ready for deployment. There are generally four levels of software testing, as mentioned below:</p>



<ol><li><a href="https://testsigma.com/blog/unit-testing/" target="_blank" rel="noreferrer noopener">Unit Testing</a></li><li><a href="https://testsigma.com/guides/integration-testing/" target="_blank" rel="noreferrer noopener">Integration Testing</a></li><li>System Testing</li><li>Acceptance Testing</li></ol>



<p>Let&#8217;s have a look at these in detail.</p>



<h3 id="h-1-unit-component-testing"><span id="1_UnitComponent_Testing"><strong>1. Unit/Component Testing</strong></span></h3>



<p>Unit testing is done at the code level, where each component is tested individually to ensure their impartiality and analyze their functionality. Automating <a href="https://en.wikipedia.org/wiki/Unit_testing" target="_blank" rel="noreferrer noopener">unit tests</a> is possible and highly recommended in today&#8217;s fast-paced development environment. To make a unit test, you should outline what you expect the code to do and write the code, which will check if it is doing what you expect. You should then run the unit test to verify that everything works as expected. For example, let&#8217;s say you have a calculator program that adds two numbers together. You can create a unit test that verifies the numerical values that the calculator program returns are correct. You could also create tests that verify edge cases and errors are handled correctly.</p>



<p>In this simple example, you could use unit testing to verify that the calculator program adds two numbers correctly.</p>



<p>First, outline and document the expectations of the program, such as:</p>



<ul><li>The program should accept two numerical values</li><li>It should return the sum of these two values</li><li>It should also handle negative numbers correctly</li></ul>



<p>You can then write unit tests that feed these values into the program and verify the correct output. For example, you could have a test that checks the program returns 2 when 1 and 1 are entered. You could have another test that checks the program returns -3 when 1 and -4 are entered. Once all the tests have been written and executed, you can confidently say that the calculator program has been successfully tested and works as expected.</p>



<h3 id="h-2-integration-testing"><span id="2_Integration_Testing"><strong>2. Integration Testing</strong></span></h3>



<p><a href="https://testsigma.com/guides/integration-testing/">Integration testing</a> enables software testers to test group units integrated into a system or subsystems; it helps identify any bugs or issues arising from coding errors or integrations between modules. It is possible to automate integration testing.</p>



<h3 id="h-3-system-testing"><span id="3_System_Testing"><strong>3. System Testing</strong></span></h3>



<p>System testing is performed on an integrated environment comprising the whole application, where all components are assessed against specific business requirements. You can use automation tools for System Testing.</p>



<p>For example, Testsigma, a no-code test automation platform, can complete end-to-end flows for web, mobile, and desktop applications and APIs.</p>



<h3 id="h-4-acceptance-testing"><span id="4_Acceptance_Testing"><strong>4. Acceptance Testing</strong></span></h3>



<p><p style="padding-bottom:30px">Acceptance testing involves testing the system&#8217;s <a href="https://testsigma.com/guides/functional-testing/" target="_blank" rel="noreferrer noopener">Functional </a>and Non-functional aspects, such as performance, security, usability, accessibility, compatibility, and reliability. Depending on the system&#8217;s complexity, it can be done manually or through automation tools. In this example, we will demonstrate the process of using Testsigma to automate the acceptance testing of a login page. First, we must create a test scenario that simulates users entering their login credentials and logging in successfully. Testsigma will automatically detect any issues with the page and report them back to us. Using Testsigma for acceptance testing, we can ensure that our login page is working as expected and ready for deployment.</p></p>

<h2 id="h-software-testing-sequence"><span id="Software_Testing_Sequence"><strong>Software Testing Sequence</strong></span></h2>



<p>Let&#8217;s talk about test sequences. It&#8217;s a fancy way of saying we need to test our software step by step. We must go through four main testing stages before we can say our software is ready.</p>



<ol><li>First up, we&#8217;ve got unit testing. This is where we test each unit or component of the software to ensure it&#8217;s doing what it&#8217;s supposed to.</li><li>Then we move on to integration testing, where we test how all the different units work together.</li><li>Next, we&#8217;ve got system testing, where we test the whole system as a complete package.</li><li>Finally, we&#8217;ve got acceptance testing, where we let the end users have a go at the software to ensure it&#8217;s meeting their needs.</li></ol>



<p>And that&#8217;s it! Four simple steps to make sure our software is top-notch.</p>

<h2 id="h-what-is-peer-review-in-software-testing"><span id="What_is_Peer_Review_in_Software_Testing">What is Peer Review in Software Testing?</span></h2>



<p>Peer review in software testing can be described in 2 ways:</p>



<p> 1. A practice of checking or reviewing the code of your fellow developer.</p>



<p> 2. It can also mean checking the test cases and scripts created by your fellow testers to provide feedback and reduce testing issues.</p>



<p>Peer reviews involve viewing and testing the functioning some code or test cases to ensure that they meets the essential requirements criteria. The aim of peer review is to highlight any possible issues the piece being reviewed, suggest improvements, and check if their compliance with standards. Peer reviews help in getting a different perspective on one’s work and receiving suggestions on making the work not only better but also easier to follow. Peer review can be considered a static testing technique.</p>



<p>There are automated tools too that support the review of <a href="https://testsigma.com/automated-testing" target="_blank" rel="noreferrer noopener">automated tests </a>like <a href="https://testsigma.com/mobile-testing-tools" target="_blank" rel="noreferrer noopener">Testsigma,</a> that is built with review workflows, enabling testers to review each other’s work.

<br><h2 id="h-why-do-we-need-peer-review"><span id="Why_Do_We_Need_Peer_Review">Why Do We Need Peer Review?</span></h2>



<p>There are many reasons why you need to adopt peer review practice in your SDLC process. And it’s more than just improving the code quality.</p>



<ul><li>The inquisitive approach of your fellow developers and testers is sure to find minute issues that might miss your eyes.</li><li>It improves communication and accessibility within the team, as everyone knows who is working on what. This kind of understanding will increase the give-and-take of information among the team members.</li><li>Peer review facilitates learning among peers and builds an environment of healthy competition.</li><li>This process helps save costs in outsourcing the reviewing task to external resources or buying tools for the exact purpose.</li><li>Peer review practice is important as it also helps developers and testers meet their deadlines by taking help from their fellow team mates to solve any blockers faced.</li></ul>



<h2 id="h-what-should-we-review"><span id="What_Should_We_Review">What Should We Review?</span></h2>



<p>There is no point in promoting peer review when you don’t know what things you should review in the first place. There is a plethora of documentation to prove that soliciting feedback results in improving the quality of the product and reducing rework. We have a list of all the necessary documents and tasks you should include in your peer review process:</p>



<ul><li>Product definition and marketing planning document to properly analyze the product’s purpose and delivery needs</li><li>User requirements/specifications documents containing all the information end-users want in the application</li><li>System design documents that consist of system architecture and UI/UX plan</li><li>Programming code reviewing involves checking the backend code and looking for defects, improvements, and flow</li><li>Test plans and test cases documents consist of the test scenario, steps, and more</li></ul>



<p></p>



<h2 id="h-types-of-peer-reviews"><span id="Types_of_Peer_Reviews">Types of Peer Reviews</span></h2>



<p>Peer review in software testing can be classified into two types: formal and informal. They differ in how they are conducted within the organization.</p>



<h3 id="h-formal"><span id="Formal">Formal</span></h3>



<p>A formal peer review is one which is led by a trained moderator and follows a particular structure. It consists of a series of tasks, including requirements walkthroughs, technical reviews, inspections, and a well-detailed report at the end.</p>



<h3 id="h-informal"><span id="Informal">Informal</span></h3>



<p>Informal peer review is the exact opposite of formal. No moderator leads the process, and it is usually a personal favor that your colleagues ask of you. It follows no structure, and there are no recorded minutes of meetings for reviewers to access.</p>



<h2 id="h-peer-review-process"><span id="Peer_Review_Process">Peer Review Process</span></h2>



<p>Follow these different ways to implement a peer review process in your company:</p>



<p><strong>Informal:</strong> Start with the informal review process that simply consists of asking a fellow developer or tester to check your code or tests for correctness and to suggest improvements.</p>



<p><strong>Walkthrough:</strong> This method consists of a software developer or tester leading peers interested in the review process. They can pose questions while reviewing and come up with their explanation/understanding of the product.</p>



<p><strong>Create a structure:</strong> For a formal review process, creating a structure and having a moderator enforce the structure upon the reviewers is the best way to go.</p>



<p><strong>Review:</strong> Start the review process formally or informally, as mentioned in the above steps.</p>



<p><strong>Verify:</strong> Verification involves an organized way of conducting the evaluation process. It involves applying several testing metrics/techniques to understand the results of the review process and to analyze the validity of the output.</p>



<h2 id="h-peer-review-static-testing"><span id="Peer_Review_8211_Static_Testing">Peer Review &#8211; Static Testing</span></h2>



<p>Peer review is a static black-box testing technique. Static testing refers to analyzing the code and the related documents without the need to execute the program and tasks. So, instead of running the tests and uncovering defects, peer review follows the static testing method, which identifies issues before executing the code.</p>



<p>Here are some examples of what undergoes testing/analysis as a part of the static testing method:</p>



<ul><li>Requirement specification documents</li><li>Design documents</li><li>Webpage content</li><li>Source code</li><li>Test plans, test cases, test scripts, and test data</li><li>User requirement documents</li></ul>



<div class="wp-block-image"><figure class="aligncenter size-full is-resized"><img loading="lazy" src="https://testsigma.com/blog/wp-content/uploads/Frame-48095885.png" alt="Testsigma - Peer Review – Static Testing" class="wp-image-30350" width="600" height="400"/></figure></div>



<p><p style="padding-top:30px">In the above image, you can see how the peer review process gradually becomes formal as it moves down across the pyramid. The picture illustrates the different stages of the peer review process that we have discussed in the above section.</p></p>



<p>Read here about <a href="https://testsigma.com/blog/peer-testing/" target="_blank" rel="noreferrer noopener">Peer Testing</a></p>



<h2 id="h-peer-review-characteristics"><span id="Peer_Review_Characteristics">Peer Review Characteristics</span></h2>



<p>The characteristics of peer review are as below:</p>



<ul><li>It is a documented way of evaluating the code that involves a defect detection process.</li><li>The higher management is not involved in peer review. It consists of peers and a few technical specialists.</li><li>The peer review team is managed by a moderator who is not the original author of the code.</li><li>Reviewers create a final report of the review, which lists and details all the issues that require attention and enhancement in the program.</li></ul>



<h2 id="h-key-takeaway"><span id="Key_Takeaway">Key Takeaway</span></h2>



<p>Peer review is a way of checking and validating the code of another developer. It is done to offer advice on making the product better and finding bugs in the code. There are different ways to perform peer review, and the most suitable one is the formal review. We have discussed the types, benefits, and processes of peer review in software testing in the above sections.</p>



<p>Peer review is a fairly easy task that takes less time than sourcing the work to outside parties, but it offers immense advantages to the business. It builds communication among the team members and creates a sense of shared responsibilities among them. And with the right approach and moderator, any peer review will only provide positive results for every code you check.</p>



<h2 id="h-frequently-asked-questions-faqs"><span id="Frequently_Asked_Questions_FAQs">Frequently Asked Questions (FAQs)</span></h2>



<h3 id="h-what-are-the-3-kinds-of-peer-review"><span id="What_are_the_3_kinds_of_peer_review">What are the 3 kinds of peer review?</span></h3>



<p>The three kinds of peer review in testing are single-anonymized, double-anonymized, and open peer review.</p>



<p>The single-anonymized peer review is where the author does not know the identity of the reviewer. In double-anonymized, both reviewer and author don’t know the identity of each other. In Open peer review, the identity of the author and reviewer are known by everyone in the reviewing team before, during, and after the peer review process.</p>



<h3 id="h-what-is-a-peer-review-example"><span id="What_is_a_peer_review_example">What is a peer review example?</span></h3>



<p>An example of peer review is deciphering the code of a developer. Suppose your colleague approached you to see their code and check if there is any possibility of making the program easy to understand and ensuring there is a smooth flow of data between the different modules/components of the code. This is a scenario where you are the reviewer, and your colleague is the author. Another example of peer review would be verifying the project specifications and design documents after receiving them from the clients and the stakeholders before moving ahead with the project.</p>



<h3 id="h-what-are-the-5-key-elements-of-peer-review"><span id="What_are_the_5_key_elements_of_peer_review">What are the 5 key elements of peer review?</span></h3>



<p>The five key elements of peer reviews are:</p>



<ul><li>Fairness in analyzing the code/documents</li><li>Appropriately selecting the right reviewers with the relevant experience</li><li>Choosing identifiable and publicly acceptable reviewers</li><li>Timely reporting of the review results</li><li>Providing helpful feedback</li></ul>
