Test Stub simulates the behavior of a module that a component depends on, while Test Driver controls the execution of the test case.

• Test Stub is used to simulate the behavior of a module that a component depends on.

• Test Driver is used to control the execution of the test case and interact with the component being tested.

• Test Stub provides canned answers to calls made during the test, while Test Driver initiates the test execution.

• Example: In a banking application, if the modu...read more

To run a selected test from a group of tests in Cucumber, you can use tags to specify which test to run.

• Add tags to the scenarios in your feature files

• Use the @CucumberOptions annotation in your test runner class to specify the tags to include or exclude

• Run the test using the test runner class with the specified tags

STLC is a systematic approach to software testing that defines the testing process from start to finish.

• STLC consists of phases like requirement analysis, test planning, test design, test execution, and test closure.

• Each phase has specific goals and deliverables to ensure the quality of the software.

• STLC helps in identifying defects early in the development cycle, reducing the cost of fixing them later.

• It ensures that the software meets the specified requirements and is ready...read more

A test automation framework consists of different components that help in organizing and executing automated tests efficiently.

• Test scripts: Actual test cases written in a programming language like Java or Python.

• Test data: Input data required for executing the test cases.

• Test environment: Configuration settings for executing tests on different platforms.

• Reporting: Generation of test reports to analyze test results.

• Logging: Recording of events and activities during test execu...read more

Best practices in test automation include proper planning, maintenance, collaboration, and continuous improvement.

• Create a solid test automation strategy before starting automation efforts.

• Use version control to manage test scripts and ensure traceability.

• Regularly review and update test scripts to maintain relevance and accuracy.

• Collaborate with developers and other team members to align automation efforts with development cycles.

• Implement continuous integration to run autom...read more

JUnit annotations like @Before, @Test, @After are used in Selenium for setup, execution, and teardown of test cases.

• Annotations like @Before are used to set up preconditions before each test method is executed.

• Annotations like @Test are used to mark a method as a test method.

• Annotations like @After are used to clean up after each test method is executed.

• Annotations like @BeforeClass and @AfterClass are used for setup and teardown tasks that need to be performed once for the e...read more

Selenium is a testing framework for web applications, while Cucumber is a tool for behavior-driven development.

• Selenium is a testing framework used for automating web applications, while Cucumber is a tool for behavior-driven development (BDD).

• Selenium supports multiple programming languages like Java, Python, etc., while Cucumber uses Gherkin syntax for writing test cases.

• Selenium focuses on automating the testing process, while Cucumber focuses on collaboration between deve...read more

BDD is a software development approach that encourages collaboration between developers, testers, and business stakeholders.

• BDD focuses on defining the behavior of a system through examples in plain text

• Uses a common language (like Gherkin syntax) to describe the expected behavior

• Tests are written in a way that they can be easily understood by non-technical stakeholders

• Promotes communication and collaboration between different team members

Automating CAPTCHA testing involves using third-party services or implementing custom solutions.

• Use third-party services like 2Captcha or Anti-Captcha to solve CAPTCHAs programmatically.

• Implement custom solutions using image recognition libraries like OpenCV to identify and solve CAPTCHAs.

• Integrate CAPTCHA solving functionality into your Selenium automation scripts for seamless testing.

Selenium has four main components: Selenium IDE, Selenium WebDriver, Selenium Grid, and Selenium RC.

• Selenium IDE: Record and playback tool for creating test cases.

• Selenium WebDriver: Automation tool for writing test scripts in various programming languages.

• Selenium Grid: Tool for running tests on multiple machines in parallel.

• Selenium RC (Remote Control): Deprecated component for running tests on different browsers.

Data flow testing is a type of white box testing that focuses on the paths that data takes through the application.

• It involves tracing the flow of data through the application to identify any potential issues or errors.

• Data flow testing helps in ensuring that data is processed correctly and efficiently.

• Examples of data flow testing techniques include control flow testing, data dependency testing, and variable definition testing.

Grouping in Cucumber allows for organizing related scenarios into logical groups for better management and execution.

• Grouping helps in organizing related scenarios together for better readability and maintenance.

• Tags are used to group scenarios in Cucumber.

• Grouping allows for running specific sets of scenarios based on tags.

• Grouping can be used to run scenarios in parallel or sequentially.

• Example: @smokeTest tag can be used to group all smoke test scenarios together.

Boundary value analysis is a software testing technique used to identify errors at boundaries of input ranges.

• It involves testing the boundaries of input ranges, including minimum, maximum, and just beyond the boundaries.

• Helps in identifying errors that may occur at the edges of input values.

• Example: If a system accepts values from 1 to 100, boundary value analysis would test inputs like 0, 1, 100, and 101.

• It is a black-box testing technique that focuses on the input domain o...read more
