10+ Nagarro Qa Automation Testing Engineer Interview Questions and Answers

Fibonacci sequence is a mathematical pattern where each number is the sum of the two preceding ones.

• Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones.

• The sequence starts with 1, 2, then each subsequent number is the sum of the two previous numbers (1+2=3, 2+3=5, 3+5=8, and so on).

• This sequence is used in estimating because it reflects natural growth patterns found in nature.

Yes, I have created the test plan document at the start of the project.

• Yes, I always create a test plan document at the beginning of a project to outline the testing approach and strategy.

• The test plan document includes details on scope, objectives, resources, schedule, and test cases.

• It helps in ensuring that all stakeholders are aligned on the testing process and expectations.

• For example, in my previous project, I created a detailed test plan document that was reviewed and ...read more

Sorting a hashmap using keys without any method involves iterating through the keys and rearranging them in ascending order.

• Iterate through the keys of the hashmap

• Compare each key with the next key and swap them if they are in the wrong order

• Continue this process until all keys are in ascending order

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 annotations used in feature files.

Testing matrix is a tool used to track test coverage and automation ROI is the return on investment from implementing automation testing.

• Testing matrix is a visual representation of test cases, test scenarios, and their coverage across different platforms, browsers, devices, etc.

• Automation ROI is the measure of the benefits gained from automation testing compared to the costs incurred in implementing and maintaining the automation framework.

• Automation ROI can be calculated by...read more

During the initial testing cycle of a project, focus is on establishing test cases, setting up test environments, and identifying potential issues.

• Creating test cases based on requirements

• Setting up test environments

• Identifying potential issues and risks

• Executing test cases and reporting defects

• Collaborating with developers to resolve issues

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: Running login and logout methods concurrently within a single t...read more

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.

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

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 dependencies on other parts of the code, making them harder ...read more

The parameter for a POST method in Postman is typically sent in the request body.

• Parameters are sent in the request body in key-value pairs

• Parameters can be sent as form-data, x-www-form-urlencoded, or raw JSON

• Example: {"key": "value"}

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();

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 before accessing it.

TestNG allows parallel execution of test cases to save time and improve efficiency.

• TestNG provides the 'parallel' attribute in the testng.xml file to specify the level of parallelism for test execution.

• Parallel execution can be achieved at the test level, class level, method level, or suite level.

• TestNG also supports parallel execution of tests across multiple classes or suites using the 'parallel' attribute in the suite tag.

• Parallel execution can be controlled using differen...read more

Use Rest Assured to upload a file

• Use the given file path to create a File object

• Use MultiPartSpecBuilder to build the request with the file

• Send the request using Rest Assured's given(), when(), and post() methods

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
