What happens when assertion fails in Selenium?
Difference between Assert and Verify in selenium In the case of assertions, if the assert condition is not met, test case execution will be aborted. The remaining tests are skipped, and the test case is marked as failed. These assertions are used as checkpoints for testing or validating business-critical transactions.
What is assert fail in TestNG?
What does "assert fail" mean in TestNG? Assert fail refers to the failure of the assertion test method. The conditions for failing depends totally on the assertion methods. When an assertion fails, they throw an exception error onto the console describing the failed test (only in hard asserts).
How do you continue execution when assertion is failing?
They don't throw an exception when an assert fails. The execution will continue with the next step after the assert statement. If you need/want to throw an exception (if such occurs) then you need to use assertAll() method as a last statement in the @Test and test suite again continue with next @Test as it is.
Why assertion is used in Selenium?
Assert in Selenium WebDriver is used for verifying or validating the scenario under test. Based on the result of the Assert, the outcome (i.e. pass/fail) of the test can be decided. A test scenario is considered as passed if the 'achieved test result' matches with the 'expected test result'.
What is assert fail?
The Assert. Fail method provides you with the ability to generate a failure based on tests that are not encapsulated by the other methods. It is also useful in developing your own project-specific assertions.
What is difference between assert and verify?
Assert: If the assert condition is true then the program control will execute the next test step but if the condition is false, the execution will stop and further test step will not be executed. whereas, Verify: There won't be any halt in the test execution even though the verify condition is true or false.
How many types of assert are there?
three typesSelenium Assertions can be of three types: “assert”, “verify”, and ” waitFor”. When an “assert” fails, the test is aborted. When a “verify” fails, the test will continue execution, logging the failure. A “waitFor” command waits for some condition to become true.

Selenium doesn't support any kind of the assertion, you have go with the frameworks ex: testNG , JUnit ... I can suggest you 2 methods for asserting multiple values using testNG by assuming you have stored multiple values in ArrayList . You may have to change the logic little based on the data structure you are using.
Which assert you have used in testNG?

What is an assertion in Selenium?
Assertions (also known as Asserts) The word Assert means to state a fact or belief confidently or forcefully. In Selenium, Asserts are validations or checkpoints for an application. Assertions state confidently that application behavior is working as expected. One can say that Asserts in Selenium are used to validate the test cases.
What is the use of assert and verify in Selenium?
Asserts and Verify methods are commonly used in Selenium for verifying or validating applications. In this tutorial, we will learn the why, when and how of using these methods to make Selenium tests more efficient.
What does asserttrue mean in a test case?
assertTrue (): This Assertion verifies the Boolean value returned by the condition. If the Boolean value is true, then the assertion passes the test case.
Why are assertions important in Selenium?
They are instrumental in verifying application behavior at critical stages. By using assertions, testing teams can determine if an application is working as it is expected to. They can also save teams the trouble of running tests that don’t need to be run if a condition is not met.
What does assert null mean?
assertNull (): This method verifies if the expected output is null. If not, the value returned is false.
What is a hard assertion?
Hard Assertions are ones in which test execution is aborted if the test does not meet the assertion condition. The test case is marked as failed. In case of an assertion error, it will throw the “ java.lang.AssertionError ” exception.
What happens when a hard assertion fails?
In a hard assertion, when the assertion fails, it terminates or aborts the test. If the tester does not want to terminate the script they cannot use hard assertions. To overcome this, one can use soft assertions.
When to use asserttrue in Selenium?
The assertTrue assert in Selenium WebDriver should be used in case you are dealing with Boolean conditions. There are two distinct ways in which you can make use of assertTrue for Selenium test automation:

What is the purpose of Assert and Verify in Selenium WebDriver?
In Selenium WebDriver, both Assert and Verify in Selenium WebDriver are primarily used for validating web applications (or websites). Based on the scenario under test for Selenium test automation, a cordial decision has to be taken whether further test scenario (or test suite) execution is required or not.
What is a testng assert?
Asserts in the TestNG framework are provided by the class org.testng.Assert. By default, Asserts in Selenium WebDriver Java are Hard Asserts. For a quick recap on TestNG, you could refer to our blog on Annotations in TestNG to get started with the TestNG framework.

What is asserttrue method?
AssertTrue method asserts that a specified condition is true. It throws an AssertionError if the condition passed to the asserttrue method is not satisfied. AssertFalse method asserts that a specified condition is false. It throws an AssertionError if the condition passed to assert false method is not satisfied. AssertEquals, AssertTrue, and AssertFalse methods are the most commonly used assertions in selenium. Generally assertions verifies whether the application is same or not when we check with our expectation.
What happens to a soft assertion when the test execution fails?
A soft assertion continues with test execution even if the assertion condition fails.
What does assert false do?
assertFalse method check whether the condition is true or not.
What does assert not same mean?
assertNotSame verifies that two objects are not equal. If two objects to refer to the same object, then an AssertionError will be thrown.
What does assert null mean?
AssertNull () is a method that verifies whether the object is null or not. If an object is null, then assertion passes the test case, and the test case is marked as "passed", and if an object is not null, then assertion aborts the test case and the test case is marked as "failed". Syntax of AssertNull () method is given below:
What is a hard assertion?
Hard Assertion is an Assertion that throws the AssertException when the test case is failed. In the case of Hard Assertion, you can handle the error by using a catch block like a java exception. Suppose we have two test cases in a suite. The first test case in a suite has an assertion that fails, and if we want to run the second case in a suit, then we need to handle the assertion error. A Hard Assertion contains the following methods:
What does assertion do in a test case?
Assertion verifies the boolean value returned by a condition. If the boolean value is true, then assertion passes the test case, and if the boolean value is false, then assertion aborts the test case by an exception. Syntax of AssertTrue () method is given below:
What are the different types of assertions?

Can you use hard assertion in testng?
Till now, we have learnt about the Hard Assertion in Web Driver using Testng framework. In hard assertion, if an assertion fails then it aborts the test case otherwise it continues the execution. Sometimes we want to execute the whole script even if the assertion fails. This is not possible in Hard Assertion. To overcome this problem, we need to use a soft assertion in testng.
