(23 Questions)
- Q1. Tell me about yourself
- Q2. Where you initialise driver
- Ans.
The driver is typically initialized in the setup method of a test automation framework.
Driver initialization is usually done in a setup method before test execution.
Commonly used methods for driver initialization include WebDriverManager, System.setProperty, and driver instantiation.
Example: WebDriverManager.chromedriver().setup();
- Q3. Driver is static or non static
- Ans.
Driver can be both static and non-static depending on the context of its usage.
Driver class can be static if it is used to initiate the WebDriver instance in a test automation framework.
Driver class can be non-static if it is used as an instance variable within a test class.
Static driver can be accessed directly without creating an object of the class.
Non-static driver requires an object of the class to be created befo...
- Q4. Difference between static and non static
- Ans.
Static variables belong to the class itself, while non-static variables belong to instances of the class.
Static variables are shared among all instances of a class
Non-static variables are unique to each instance of a class
Static variables are initialized only once, at the start of the program
Non-static variables are initialized separately for each instance of the class
- Q5. Disadvantages of static and non static
- Ans.
Static and non-static have their own disadvantages in QA automation testing.
Static methods cannot be overridden or inherited, making it difficult to create flexible test cases.
Non-static methods require an instance of the class to be created, which can lead to increased memory usage.
Static methods can lead to tight coupling between classes, making it harder to maintain and update the code.
Non-static methods may have de...
- Q6. Parallel execution in TestNG
- Ans.
TestNG allows parallel execution of test cases to save time and improve efficiency.

TestNG also supports parallel execution of tests across multiple classes or suites using the 'parallel' attribute in the sui...
- Q7. Write the code for Parallel testing in TestNG
- Ans.
Parallel testing in TestNG allows running tests concurrently for faster execution.
Use 'parallel' attribute in testng.xml file to specify parallel execution mode.
Set 'parallel' attribute to 'methods', 'classes', or 'tests' based on the level of parallelism needed.
Example: <suite name='MySuite' parallel='tests'>
Use 'thread-count' attribute to specify the number of threads to use for parallel execution.
- Q8. Difference between parallel methods and parallel tests
- Ans.
Parallel methods run multiple methods concurrently within a single test, while parallel tests run multiple tests concurrently.
Parallel methods execute multiple methods within a single test class concurrently.
Parallel tests execute multiple test classes concurrently.
Parallel methods are useful for speeding up the execution of a single test, while parallel tests are useful for running multiple tests faster.
Example: Runni...

Step definitions in code map Gherkin steps to executable code, often written in Java, Ruby, or JavaScript.
Cucumber executes scenario...
- Q14. How cucumber know step defination file placed
- Ans.
Cucumber knows the step definition file based on the annotations provided in the feature files.
Cucumber uses annotations like @Given, @When, @Then to map steps in feature files to corresponding step definition methods.
Step definition files are typically placed in a separate package or directory within the project structure.
Cucumber scans the project directory for step definition files based on the package structure and...
- Q15. Parameters used in cucumber
- Ans.
Parameters used in cucumber are used to pass values to the step definitions in feature files.
Parameters are defined in feature files using < > syntax
Parameters can be passed to step definitions using Regular Expressions
Parameters can be used to make scenarios more reusable and dynamic
- Q16. Datatable in cucumber
- Ans.
Datatable in Cucumber is used to pass multiple sets of data to a step definition in a scenario.
Datatables are defined using pipes (|) to separate values
Each row in the datatable represents a set of data passed to the step definition
Datatables can be used for parameterization and data-driven testing
