You can divide the test cases into two batches and run them separately.

• Divide the 100 test cases into two batches of 50 each

• Run the first batch of 50 test cases

Step definitions can be integrated with feature files using Cucumber in automation testing.

• Create step definitions in a separate file using the same language as the feature file (e.g. Java for Cucumber-JVM).

• Map step definitions to feature file scenarios using annotations like @Given, @When, @Then.

• Use regular expressions to match step definitions with steps in the feature file.

• Run the feature file with the step definiti

Stale element reference exception occurs when an element is no longer attached to the DOM.

• Occurs when an element is located in the DOM, but later removed or modified

• Common in dynamic web applications where elements change frequently

• Can be resolved by re-locating the element before interacting with it

Microservices are small, independent services that work together, while monolithic is a single, large application.

• Microservices are loosely coupled, allowing for independent development and deployment.

• Monolithic applications are tightly integrated, making it harder to scale and maintain.

• Microservices communicate through APIs, while monolithic applications have all components within the same codebase.

• Examples of microse...read more
