What is assertTrue in Python?

This function will take two parameters as input and return a boolean value depending upon the assert condition. If test value is true then assertTrue() will return true else return false.
What is == and equals in Java?
In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects. If a class does not override the equals method, then by default it uses the equals(Object o) method of the closest parent class that has overridden this method.
What does assertEquals do in Java?
assertEquals() methods checks that the two objects are equals or not. If they are not, an AssertionError without a message is thrown. Incase if both expected and actual values are null, then this method returns equal.
How many arguments can a assertEquals method have?
Procedure assertEquals has two parameters, the expected-value and the computed-value, so a call looks like this: assertEquals(expected-value, computed-value); Note the order of parameters: expected-value and computed-value. Therefore, do not write the first call this way: assertEquals(C.
How do you assert assertEquals?
Assert. assertEquals() methods checks that the two objects are equals or not. If they are not, an AssertionError without a message is thrown. Incase if both expected and actual values are null, then this method returns equal.
Does assertEquals use equal?
Yes, it calls equals and there is a separate method, assertSame , that uses == . Just to clear things up, assertEquals works with any object since all objects declare equals . Yes it does. So as you can see it uses equals .
Which annotation helps you to disable a test method?
If you want to ignore a test method, use @Ignore along with @Test annotation. If you want to ignore all the tests of class, use @Ignore annotation at the class level.

Which is true In JUnit assert and assertEquals?
Since string1= “Junit” which is a non-null value so assertNotNull (string1) will return true. “assertNull ()” functionality is to check that an object is null. Since string5= null which is a null value so assertNull (string5) will return true.
