assumeTrue()
This assumeTrue() method is used for checking the condition of the test case. If the assumeTrue() condition is true, then run the given test case otherwise the test will be aborted.
Example:
Java
import org.junit.jupiter.api.Test; import static org.junit.jupiter.api.Assertions.assertEquals; import static org.junit.jupiter.api.Assumptions.assumeTrue; public class AddTwoNumbersTest { @Test void testAddition() { int num1 = 2; int num2 = 3; // Assume that the sum of two positive numbers is always greater than zero assumeTrue(num1 > 0 && num2 > 0); // If the assumption is true, the test continues to this point int sum = addNumbers(num1, num2); assertEquals(5, sum, "Sum should be 5"); } private int addNumbers(int a, int b) { return a + b; } } |
In the code we have used assumeTrue() method for checking the given two number num1 and num2 are greater than 0. If assumeTrue condition is true, then they will be passed. Otherwise, it is aborted. In this case test case will be passed.
JUnit 5 – Assumptions
Assumptions is one the features of JUnit 5, and the JUnit 5 Assumptions are collections unity methods that support conditional-based test case executions of software applications. One more thing Assumptions are used whenever don’t want to continue the execution of given test methods, And the Assumptions run test cases only if the conditions are evaluated to be true. In Assumptions lot of methods are available for different functionalities. Now I will explain available methods in Assumptions of JUnit 5 and mostly these methods assumingThat(), assumeTrue(), and assumeFalse() are used to Validate for given Assumptions and the method type is static void.
- assumingThat
- assumeTrue
- assumeFalse
