<h3>What is

API Automation Testing
</a>?
</h3>
<p>
API Automation Testing is the process of automatically validating APIs to ensure they function correctly,
return accurate responses, and handle errors properly without manual testing.
</p>

<h3>Why API Automation Testing is Important</h3>
<ul>
<li>Faster testing compared to UI testing</li>
<li>Early detection of backend issues</li>
<li>Stable and reliable test execution</li>
<li>Ideal for CI/CD pipelines</li>
<li>Reduces manual effort and human error</li>
</ul>

<h3>What Can Be Tested in APIs?</h3>
<ul>
<li>HTTP status codes (200, 201, 400, 401, 500)</li>
<li>Request and response body validation</li>
<li>Headers and authentication tokens</li>
<li>Data accuracy and schema validation</li>
<li>Error handling and edge cases</li>
<li>Performance and response time</li>
</ul>

<h3>Types of API Testing</h3>
<ul>
<li><strong>Functional Testing</strong> – Validates API functionality</li>
<li><strong>Integration Testing</strong> – Checks communication between services</li>
<li><strong>Regression Testing</strong> – Ensures APIs work after updates</li>
<li><strong>Performance Testing</strong> – Measures speed and load handling</li>
<li><strong>Security Testing</strong> – Validates authentication and authorization</li>
</ul>

<h3>API Automation Testing Workflow</h3>
<ol>
<li>Understand API requirements</li>
<li>Identify endpoints and HTTP methods</li>
<li>Write automated test cases</li>
<li>Execute tests</li>
<li>Validate responses</li>
<li>Generate test reports</li>
<li>Integrate with CI/CD pipeline</li>
</ol>

<h3>Common API Automation Tools</h3>
<ul>
<li>Keploy</li>
<li>Postman</li>
<li>Rest Assured</li>
<li>SoapUI</li>
<li>JMeter</li>
</ul>

<h3>Best Practices</h3>
<ul>
<li>Test both positive and negative scenarios</li>
<li>Keep test cases independent</li>
<li>Reuse test data where possible</li>
<li>Validate response schema</li>
<li>Automate authentication handling</li>
<li>Run tests regularly in CI/CD pipelines</li>
</ul>

<h3>Key Takeaway</h3>
<p>
API Automation Testing is essential for modern software development as it improves backend reliability,
speeds up testing cycles, and ensures high-quality software releases.
