Question

What are the assertion methods used by JUnit to write Selenium scripts?

Answer 1

@Vinay, JUnit provide these assertions to write Selenium Scripts:

1. assertEquals: Checks if the two values are equal and assertion fails if both values are not equal. This compares Boolean, int, String, float, long, char etc.

Syntax:

Assert.assertEqual(“excepted value”, ”actual value”);

Example:

Assert.assertEqual(“ABC”,”ABC”); // Assertion will pass.

2. assertTrue: Returns true if the condition is true and assertion fails if the condition is false.

Syntax:

Assert.assertTrue(“message”, condition);

Example:

Assert.assertTrue(“Both the strings are not equal”, (“HelloWorld”).equals(“HelloWorld”));

Here assertion will pass as both the strings match. It will print the message if the assertion fails.

3. JUnit assertFalse: Returns true if the condition is false and assertion fails if the condition is true.

Syntax:

Assert.assertFalse(“message”, condition);

Example:

Assert.assertFalse(“Both the strings are equal”, (“Hello”).equals(“HelloWorld”));

There will not be any assertion error as the condition is false.
