Question

Accepted Answer

Answers to various technical questions related to automation testing and software development.

findElements vs findElement: findElements returns a list of web elements matching the locator, while findElement returns the first web element matching the locator.
Set vs Map: Set is a collection of unique elements, while Map is a collection of key-value pairs.
Program for occurrences of characters: Write a program to count the occurrences of each character in a given string.
Program for Fibonacci series: Write a program to generate the Fibonacci series up to a certain number of terms.
How to get values from dropdowns: Use Selenium WebDriver methods like getOptions() or selectByVisibleText() to interact with dropdown elements.
Smoke vs Sanity: Smoke testing is a subset of regression testing to check if the critical functionalities are working, while sanity testing is a narrow regression testing to check if the specific changes are working.
Bug Life Cycle: Bug life cycle includes stages like New, Assigned, Fixed, Verified, Reopened, and Closed.
Regression and retesting: Regression testing ensures that new code changes do not adversely affect existing functionalities, while retesting is done to verify if a specific bug has been fixed.
Merge and rebase: Merge combines changes from different branches into one, while rebase moves the entire feature branch to begin from the tip of the master branch.
How to run Jenkins: Jenkins can be run by starting the Jenkins server using the command line or by running it as a service.
Connecting files in Cucumber: Files can be connected in Cucumber using the 'glue' option in the CucumberOptions annotation.
Hooks: Hooks in Cucumber are blocks of code that run before or after each scenario.
Running flaky test cases: Flaky test cases can be run multiple times using a retry mechanism to reduce the chances of false failures.
Priority in TestNG: TestNG allows setting priorities for test methods using the 'priority' attribute in the @Test annotation.

Accepted Answer

diff b/w findelements vs findelement
findElements fetch multiple elements and returns as List<Webelement>

findElement fetch single web elements and returns as Webelement
