<h2 id="h-what-is-local-testing"><span id="What_is_local_testing">What is local testing?</span></h2>



<p>Local testing is the practice of testing software applications on physical devices located on your premises or within your network. It involves testing applications on local machines rather than relying solely on cloud-based solutions. This approach offers numerous benefits, including real-world testing, faster feedback loops, cost efficiency, and enhanced data privacy and security.&nbsp;</p>



<h2 id="h-why-is-local-testing-needed"><span id="Why_is_local_testing_needed">Why is local testing needed?:</span></h2>



<p>Before we dive into the how, let&#8217;s first understand the why. Local testing is a game-changer for developers, and here&#8217;s why:</p>



<h3 id="h-real-world-testing"><span id="Real-world_Testingnbsp">Real-world Testing:&nbsp;</span></h3>



<p>With local testing, you&#8217;re not relying on simulated environments or remote servers. You&#8217;re testing your application on the very devices your users will use. This means you can catch those pesky device-specific bugs that often slip through the cracks.</p>



<h3 id="h-faster-feedback-loops"><span id="Faster_Feedback_Loopsnbsp">Faster Feedback Loops:&nbsp;</span></h3>



<p>When your testing happens locally, you can quickly iterate and make changes based on real-time feedback—no more waiting for results from distant servers.</p>



<h3 id="h-cost-efficiency"><span id="Cost_Efficiencynbsp">Cost Efficiency:&nbsp;</span></h3>



<p>Cloud testing services can rack up significant costs, especially for extensive testing. Local testing can be far more cost-effective, making it an attractive option for startups and small businesses.</p>



<h3 id="h-data-privacy-and-security"><span id="Data_Privacy_and_Securitynbsp">Data Privacy and Security:&nbsp;</span></h3>



<p>Some applications deal with sensitive data that shouldn&#8217;t leave your premises. Local testing ensures that your data stays where it belongs – under your control.</p>

<h3 id="h-what-is-an-api"><span id="What_is_an_API"><strong>What is an API?</strong></span></h3>



<p>An application programming interface (API) is a set of rules that define how applications can communicate with each other. There are different <a href="https://testsigma.com/blog/different-types-of-apis-and-protocols-2022-updated/" target="_blank" rel="noreferrer noopener">types of APIs</a> like GraphQL, REST, WebSocket APIs, RPC APIs, etc. All APIs have their own set of protocols and definitions. So each API type operates differently. </p>



<p>API is simple to implement and will have a lightweight architecture. It is often assumed that APIs are web APIs, that is information is exchanged over the internet. However, APIs can also be exposed using local files such as JAR without the internet. Web APIs are the most common and widely used.</p>



<p id="components-of-api"><strong>Components of API</strong></p>



<p>APIs are very lightweight, it involves three main components.</p>



<ul><li>Client: A client can be any external or internal application that makes the request.</li><li>Server: A server executes the program and sends the response.</li><li>API contracts: Request response formats are also known as API contracts.</li></ul>



<p>Read here &#8211; <a href="https://testsigma.com/blog/api-examples/" target="_blank" rel="noreferrer noopener">API Examples</a></p>



<h3 id="h-what-is-a-web-service"><span id="What_is_a_Web_Service"><strong>What is a Web Service?</strong></span></h3>



<p>Web service is a software system designed to support interoperable machine-to-machine communication over the Internet. Web services are designed to provide a specific set of services. Developers can utilize multiple web services to build a single functionality which helps in code reusability and reduces the time and cost of development.</p>



<p>Webservices require a network to interact and network communication is generally achieved using Simple Object Access Protocol (SOAP). SOAP uses XML format for encoding data. The XML format is used for storing and transferring information using HTTP protocol. </p>



<p>An application sends the requests to a service in XML format. Services then see and process the request and reply to the application as response using the same XML format. Web services can follow <a href="https://testsigma.com/blog/api-rest-vs-soap/" target="_blank" rel="noreferrer noopener">SOAP or REST</a> principles for implementation. However, SOAP is the most widely used.</p>



<p id="types-of-webservices"><strong>Types of Webservices</strong></p>



<p>Web Services can be broadly classified into two different types as given below</p>



<ul><li><strong>SOAP Web Service:</strong> SOAP is a legacy protocol. Designed before REST.  SOAP became popular as it provides an efficient and secure way to exchange data independent of the software platform.</li><li><strong>REST Web Services:</strong> REST is more helpful when your application requires manipulation or exchange of media files, objects, or objects on a hardware device. The service needs to fully adhere to <a href="https://www.knowledgehut.com/blog/programming/rest-api">REST principles</a> to claim the service as a RESTful service. The HTTP verbs such as GET, POST, PUT, and DELETE are used as commands for information exchange.</li></ul>





<h2 id="web-service-vs-api-examples"><span id="Web_Service_vs_API_Examples"><strong>Web Service vs API – Examples</strong></span></h2>



<p>APIs are often used to integrate data and functionality from one software application into another. </p>



<p>For example, a weather app might use the OpenWeatherMap API to retrieve weather data, or a social media app might use the X (Twitter) API to allow users to post tweets.</p>



<p>Web services often provide complete user interfaces for interacting with data and functionality. </p>



<p>For example, Google Maps is a web service that provides users with a map interface for searching for locations and directions.</p>



<p>It is important to note that some web services also provide APIs. For example, the Google Maps web service also provides an API that developers can use to integrate Google Maps functionality into their applications.</p>



<p>Here are some examples we use in our day-to-day life.</p>



<p><strong>Examples of APIs</strong></p>



<ul><li><strong>Google Search API:</strong> This API allows you to blend Google Search functionality into their applications.</li><li><strong>X(Twitter) API:</strong> This API allows access and interaction with <strong>X</strong>(Twitter) data.</li><li><strong>Facebook API:</strong> This API allows access to and interact with Facebook data.</li><li><strong>PayPal API:</strong> This API allows the integration of PayPal payment processing into their applications.</li><li><strong>OpenWeatherMap API:</strong> This API allows you to access weather data from all over the world.</li></ul>



<p><strong>Examples of Web Services</strong></p>



<ul><li><strong>Google Maps:</strong> This web service allows users to view and interact with maps of the world.</li><li><strong>Amazon Web Services:</strong> This web service provides a wide range of cloud computing services, including storage, computing, and networking.</li><li><strong>PayPal:</strong> This web service allows users to send and receive money online.</li><li><strong>Netflix:</strong> This web service lets users stream movies and TV shows online.</li><li><strong>Spotify:</strong> This web service allows users to stream music online.</li></ul>



<h2 id="differences-between-web-services-and-api"><span id="Differences_Between_Web_Services_and_API"><strong>Differences Between Web Services and API</strong></span></h2>

<p></p>





<p id="what-to-test-in-api-testing"><strong>What to Test in API Testing?</strong></p>



<p>API Testing is most critical as it is the middle layer. APIs usually communicate with UI and Database. You can test a lot more in API testing. However, at the minimum, you need to test below key areas.</p>



<ul><li>Response Code</li><li>Response Payload</li><li>Response headers</li><li>API Contracts</li></ul>



<p>Remember, While doing API testing you need to focus on both happy flows, sad/error flows, and edge case scenarios.</p>



<p>It is recommended to perform API testing as much as possible. Compared to UI tests API test are more stable and takes less time to execute. The data and major chunk of application functionality can be tested using <a href="https://testsigma.com/guides/api-testing/">API testing</a>.<br>The web service and APIs are not the same, they exist to solve different problems. The modern web application architecture emphasizes API-driven development. So web APIs are most commonly used across the industry. API also simplifies complex application development and helps in code re-usability and security. API can be implemented in different ways based on needs and other organization-related factors. As the development is aligning with web API the need for API testing is more. Most organizations follow API testing as integration testing as major data-related functionality can be tested within a few minutes. Most of the automation tools support API testing however, setting up an API testing framework takes more time. Importantly, the requirement for skilled resources is a major challenge. Tools like Testsigma make API testing easier and faster. It also comes with DevOps (CI/CD) integration thus it makes developer/tester friendly.</p>



<h2 id="summary"><span id="Summary"><strong>Summary</strong></span></h2>



<p>In conclusion, web services are a specialized subset of APIs that adhere to specific standards, while APIs offer a more flexible and versatile approach to application integration. Though all web services are APIs, not all APIs are web services: APIs can use any number of protocols and be local or remote.</p>
