This Java Automation course is crafted for experienced QA professionals, test automation engineers, and SDETs who want to go deeper into the design, structure, and scalability of test automation systems.

You’ll gain deep expertise in Core Java, Selenium WebDriver, REST Assured, and JUnit, with a strong focus on building robust, reusable, and maintainable automation frameworks for UI and API testing.

You will also learn how to plan for modular automation, manage test data, structure your codebase, and apply best practices to ensure high-quality and efficient testing.

  • Updating data using UPDATE
  • Deleting data using DELETE

• Joins in SQL

  • Understanding different types of joins: INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL JOIN
  • Retrieving data from multiple tables using joins

• Aggregating Data

  • Grouping data using GROUP BY
  • Filtering groups with HAVING clause

• Indexes and Keys

  • Understanding primary keys and foreign keys
  • Using indexes for performance optimization

• Basic Database Testing

  • Verifying data integrity with SQL queries
  • Validating test scenarios using SQL

🌐 Web Services and REST API

• What are Web Services?
• REST vs SOAP
• Components of REST API
• HTTP Methods: GET, POST, PUT, DELETE, PATCH
• HTTP Status Codes: 1xx–5xx
• Tools: Postman, curl
• Parsing JSON/XML
• Error Handling
• Examples using Flask & Express.js

🔁 API Automation using REST Assured

• What is REST-Assured?

  • A Java-based library used to test RESTful APIs.
  • Provides a domain-specific language (DSL) for writing readable and maintainable API tests.
  • Integrates seamlessly with Java-based testing frameworks like JUnit and TestNG.

• Setting up with Maven

  • Add REST-Assured dependency in your pom.xml.

    <dependency>
        <groupId>io.rest-assured</groupId>
        <artifactId>rest-assured</artifactId>
        <version>5.3.0</version>
        <scope>test</scope>
    </dependency>
    

  • Optionally include JSON/XML path and Hamcrest matchers for assertions.

• HTTP Method Testing

  • GET: Retrieve data from an API.
  • POST: Send data to the server.
  • PUT: Update existing data.
  • DELETE: Remove data from the server.
  • PATCH: Partially update resources.

• Validating Responses

  • Status Code
    • Validate HTTP response code (e.g., 200 OK, 404 Not Found).
  • Headers
    • Assert presence and values of headers like Content-Type, Authorization, etc.
  • Body
    • Validate fields in JSON or XML response using path expressions.

• Authentication

  • Basic Authentication
    • Pass credentials using .auth().basic(username, password).
  • Token-Based Authentication
    • Use .auth().oauth2(token) for Bearer tokens (commonly used in REST APIs).
  • Custom Headers
    • Add custom Authorization headers when needed.

• Request Parameters & Payloads

  • Query Parameters
    • Use .param("key", "value") or .queryParam().
  • Path Parameters
    • Define placeholders in the endpoint URL.
  • Request Body
    • Send JSON, XML, or form data as payload using .body().

• Assertions with Hamcrest

  • Use expressive matchers for validating response:
    • equalTo(), hasItems(), containsString(), etc.
  • Enables readable assertions like:

    then().body("name", equalTo("John"));
    

• Logging and Configurations

  • Enable request and response logging:
    • .log().all() or .log().body()
  • Configure timeouts, proxies, and base URI using RestAssured.config.

• File Uploads/Downloads

  • Upload files using .multiPart() method.
  • Download files and validate content type, size, etc.

• TestNG / JUnit Integration

  • Use REST-Assured inside test methods.
  • Combine with test annotations for setup, teardown, and grouping.
  • Create reusable test suites and CI pipelines.

• Best Practices and Hands-on

  • Use RequestSpecification and ResponseSpecification for reusability.
  • Externalize base URIs, endpoints, and payloads in config files or constants.
  • Follow clear naming conventions and logging to maintain readable tests.
  • Hands-on practice: Create CRUD tests against public APIs like https://reqres.in or your own mock server.
