<h2 id="h-what-is-sandwich-testing"><span id="What_Is_Sandwich_Testing">What Is Sandwich Testing?</span></h2>



<p>Sandwich testing is an integration testing method that involves splitting an application into different layers and testing them separately and integrally to ensure each layer works perfectly to meet the software specifications. You can also refer to a sandwich test as hybrid integration testing since it combines the top-down and bottom-up testing approaches. Sandwich testing is an incremental testing process, and it assumes a three-layer testing pattern with the middle layer as the target layer.</p>



<h3 id="h-the-top-down-testing-approach"><span id="The_Top-Down_Testing_Approach">The Top-Down Testing Approach</span></h3>



<p>The top-down approach starts testing from the middle layer (target) to the lower modules. Here, you begin with the independent validation of individual units of the target layer, followed by a gradual integration of the lower modules, usually the database and other external services.&nbsp;</p>



<p>The lower modules are usually stubbed (simulated) to provide dummy data and objects to mimic them. This helps verify if the validated component of the target layer behaves as expected when mounted on lower subsystems.</p>



<h3 id="h-the-bottom-up-approach"><span id="The_Bottom-Up_Approach">The Bottom-Up Approach</span></h3>



<p>On the other hand, the bottom-up approach begins testing from the middle layer to the upper modules. This approach first evaluates the upper part in isolation and gradually tests it when integrated with the validated middle subsystem to catch bugs as the test proceeds. You can think of the upper layer in context as a simulated UI.</p>



<h3 id="h-sandwich-testing-and-the-n-tier-software-architecture"><span id="Sandwich_Testing_and_the_N-Tier_Software_Architecture">Sandwich Testing and the N-Tier Software Architecture</span></h3>



<p>An N-tier software architecture using a three-tier typically features the client side, business logic, and data access. You test each layer independently and further validate how they communicate after integration. That&#8217;s the sandwich testing concept. Ultimately, it helps mitigate bugs and save development time. Additionally, it makes your test suite more scalable since there are different test layers.</p>



<p>For instance, while ensuring that the submit button in the UI works, you also want to ensure that it calls the appropriate function, sends the expected queries to the database, and executes the associated algorithm expectedly on the returned data. Regardless of your application&#8217;s complexity, the sandwich testing method helps your test assess its entire architecture without complicating your test suite.</p>



<h2 id="h-features-of-sandwich-testing"><span id="Features_of_Sandwich_Testing">Features of Sandwich Testing</span></h2>



<p>Here are the key features of sandwich testing.&nbsp;</p>



<ul><li><strong>Sandwich testing is granular</strong>: It’s specific to each component or feature of an application. Thus, it involves independently testing individual components and how they further communicate with the corresponding subsystems. Invariably, it ensures each application component satisfies its expected quality first and checks how it behaves when it works with its associated layers.</li><li><strong>It assumes a three-layer testing pattern</strong>: Sandwich testing takes the bottom-up and top-bottom approach, with the target layer is typically in the middle.</li><li><strong>It is complete</strong>: Sandwich testing has extended coverage, combining integration and unit testing to validate the target layer independently first. It then verifies how it works when integrated with the associated upper and lower layers.</li><li><strong>It modularizes the test suite</strong>: Sandwich testing ensures that the test suit handles each part of an application under test independently, separating component concerns into modules that can run independently.<strong>&nbsp;</strong></li><li><strong>Sandwich testing is incremental</strong>: Sandwich testing typically starts with the target module and progresses to other components in a forward and reverse pattern (from middle to top and from middle to bottom).</li></ul>



<h2 id="h-why-is-sandwich-testing-necessary-in-software-testing"><span id="Why_is_sandwich_testing_necessary_in_software_testing">Why is sandwich testing necessary in software testing?</span></h2>



<p>The ultimate goal of sandwich integration testing is to ensure that each subsystem of your application works together to achieve an overall quality. While it might be costly and complex, you want to use this testing method for the following reasons.</p>



<ul><li><strong>Earlier bug detection</strong>: It helps catch potential bugs earlier, saving development time and mitigating financial loss from production bugs.</li><li><strong>Improved test coverage</strong>: It helps you perform both unit and integration testing simultaneously to discover the effect of integrating other subsystems on the target layer. So, it improves the<a href="https://testsigma.com/blog/test-coverage/" target="_blank" rel="noreferrer noopener"> test coverage</a> and software quality.</li><li><strong>Test scalability and reusability</strong>: Since each test module handles the application’s components individually, sandwich testing makes it easy to add more tests and reuse existing ones as your application scales. Thus, it’s robust and ideal for testing applications with complex architecture.</li><li><strong>Reduced test suite complexity</strong>: Sandwich testing adopts a descriptive naming convention, making locating the module that handles a specific test easier. It also makes your tests more comprehensive when shared with your team.</li><li><strong>Support for parallel testing</strong>: You can test modules in parallel since many modules are under test. This saves time significantly.</li><li><strong>Support for test automation</strong>: Like conventional end-to-end testing, sandwich testing is also subject to automation testing tools like Testsigma, Selenium, Appium, Playwright, and many more.</li></ul>



<h2 id="h-sandwich-testing-and-test-automation"><span id="Sandwich_testing_and_test_automation">Sandwich testing and test automation</span></h2>



<p>Automating your sandwich testing is helpful when:</p>



<ul><li>Considering the complexity of sandwich testing, automation simplifies the process</li><li>Test automation improves the test feedback cycle, allowing the development team to evaluate test results more efficiently.&nbsp;</li><li>Automation testing is saving costs, some avenues where costs can be saved are:<ul><li>It simulates different testing environments, including browsers and operating systems.</li><li>It helps you track the test step that fails during testing. This is handy for quick bug fixing.</li><li>It helps keep track of the test for continuity and scalability.</li><li>Automating your sandwich test provides an avenue for parallel multi-platform and multi-browser testing.</li></ul></li></ul>



<h3 id="h-some-tools-to-automate-sandwich-testing"><span id="Some_Tools_to_Automate_Sandwich_Testing">Some Tools to Automate Sandwich Testing</span></h3>



<ul><li><strong>Testsigma</strong>: Testsigma is an automation testing platform that allows you to automate UI tests locally or in the cloud without coding, in simple English. With support for multi-browser and multi-device testing, you can run tests in parallel using Testsigma’s Test Lab. In addition to browser extensions for recording tests, it features a user-friendly interface for creating test scenarios and writing test steps for each. It supports web, mobile, and API testing with little maintenance overhead, as tests are in plain English script.&nbsp;</li></ul><br>



<p><button class="btn bg-primary cta-btn" style="margin: auto"><a href="https://testsigma.com/signup" target="_blank" rel="noopener noreferrer" style="color:#fff">Automate your tests for web, mobile, desktop and APIs from the same place, 10x faster, with Testsigma</a></button></p>



<br><ul><li><strong>Selenium</strong>: Selenium is an open-source framework for automating user interactions on the web. Selenium provides web drivers for modern browsers, including Chromium-based browsers, Firefox, and Safari, and it&#8217;s the most-used testing framework. As of writing, Selenium has approximately 206,000 users, according to its <a href="https://github.com/SeleniumHQ/selenium" target="_blank" rel="noreferrer noopener">GitHub stat</a>. The framework also features an IDE for playback test automation and supports the Selenium Grid for orchestrating tests in multiple environments. Selenium test automation requires coding experience in its supported languages, including Python, Kotlin, Ruby, Java, JavaScript, and C#.</li></ul><br>



<ul><li><strong>Playwright</strong>: Playwright is Microsoft&#8217;s end-to-end testing framework for automating web actions. In contrast to Selenium, <a href="https://github.com/microsoft/playwright" target="_blank" rel="noreferrer noopener nofollow">GitHub</a> puts its users&#8217; stat at 26,000. Compared to Selenium, Playwright is more recent and supports fewer programming languages, including JavaScript, Python, TypeScript, .NET, and Java. It also supports many modern browsers and allows parallel testing. Unlike Selenium, which requires an implicit wait for DOM loading, Playwright features auto-wait and web-first assertions. The framework also has a code generator. In addition to helping set up tests quickly, this can be handy for generating relevant web element selectors during testing to save element inspection time.</li></ul>



<h2 id="h-example-of-sandwich-testing"><span id="Example_of_Sandwich_Testing">Example of Sandwich Testing</span></h2>



<p>Every application has different components performing different functions. Each part typically communicates with the lower subsystems. These include the business logic and data layers.&nbsp;</p>



<p>In sandwich testing, the application validation is typically incremental. It ensures you verify one module after another when integrated with the top layers.&nbsp;</p>



<p>While performing sandwich testing, you typically start by testing the UI using stubs to simulate test data. Here, you might want to use UI testing tools like Testsigma to simulate a UI to validate the target component.</p>



<p>Once you test the UI, you can start testing the lower modules independently using drivers to simulate unavailable modules. Once done, you&#8217;ll integrate each validated lower module with the UI and rerun the test. This is the <a href="https://testsigma.com/blog/system-integration-testing/" target="_blank" rel="noreferrer noopener">integration testing</a> phase. It verifies if the application works expectedly after mounting each module.</p>



<p>For example, while testing a complex application using the sandwich approach, you want to validate each lower module in isolation before integrating it with the target (the UI). Next, you&#8217;ll rerun the test after integrating the UI with the previously validated module. This is to validate that each module works as expected when mounted on the UI.&nbsp;</p>



<p>You then repeat the process for each lower module until your test satisfies the required quality. However, modules that are unavailable for testing are usually stubbed.</p>



<h2 id="h-how-to-run-a-sandwich-test"><span id="How_to_run_a_sandwich_test">How to run a sandwich test?</span></h2>



<p>Sandwich testing requires close attention to the detail of your application. The following steps are a guide for executing a sandwich test.</p>



<p><strong>Step 1: Create your test scenarios</strong>: Planning a test scenario helps you imagine a user story. Your test scenario must be complete, comprehensive, and realistic and should include concise test steps.</p>



<p><strong>Step 2</strong>: <strong>Prioritize the essential modules</strong>: Identifying the target components makes your tests more specific and consistent. Ensure you collaborate with the development team to understand underlying functions and modules. This helps you to verify which modules are available for testing and efficiently create test stubs and drivers for them. At this stage, you also want to identify and prioritize the modules in the order of their effect on your application&#8217;s functionalities.</p>



<p><strong>Step 3</strong>: <strong>Choose a testing environment</strong>: This is where you decide whether to run manual or automation testing. While automating your test, you should also determine whether to use a local web driver or spin it up using a cloud grid.</p>



<p><strong>Step 4</strong>: <strong>Run your UI test in isolation</strong>: Start your sandwich testing by running the UI test in isolation with stubs.</p>



<p><strong>Step 5: Test each module independently</strong>: Here, you’ll test each lower subsystem in isolation to ensure they meet the software quality requirements. You might want to run subsystem <a href="https://testsigma.com/blog/performing-parallel-testing-in-testsigma/" target="_blank" rel="noreferrer noopener">tests in parallel</a> to save time and cost.</p>



<p><strong>Step 6: Perform integration testing on mounted modules</strong>: After testing each module and the UI independently, integrate the UI with each module<strong> </strong>and rerun the test.&nbsp;&nbsp;</p>



<p><strong>Step 7: Evaluate test results</strong>: Use various test coverage and analytic tools to estimate how well your test performed. A critical evaluation of the test coverage helps you identify further test requirements. You can also generate shareable HTML coverage reports to view the missing tests.</p>



<h2 id="h-summary"><span id="Summary">Summary</span></h2>



<p>Despite the independence of each layer during development, they intertwine and work together when shipped to the end user. Bugs in one of the layers can break the whole. Thus, a layered architecture requires unsullied testing to ensure all parts meet software quality standards and user experience expectations.&nbsp;</p>



<p>Unlike integration testing, that only tests the software when systems are mounted, sandwich testing is more comprehensive, as it checks each layer separately before integrating them incrementally with the target layer.</p>

<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>

<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>
