Assumptions is a collection of utility methods that support conditional test execution based on assumptions. Failed assumptions do not result in a test failure; rather, a failed assumption results in a test being aborted.
Assumption basically means “don’t run this test if these conditions don’t apply”.
Junit 5 comes with a subset of the assumption methods that JUnit 4 provides with Java 8 lambda expressions and method references. All JUnit Jupiter assumptions are static methods in the
1. Junit 5 Assumptions:
Assumptions.assumeTrue() – If the condition is true, then run the test, else aborting the test.
Assumptions.false() – If the condition is false, then run the test, else aborting the test.
Assumptions.assumingThat() – If condition is true then executes, else do not abort test continue rest of code in test.
Lets have a look into Juint 5 Assumptions in below example.
