Complete the code to enable the test only if the environment variable 'ENV' equals 'test'.

JUnit

@EnabledIfEnvironmentVariable(named = "ENV", matches = "[1]")
void testFeature() {
    // test code here
}

💡 Hint

Common Mistakes

Using the wrong environment variable value in 'matches'.

Forgetting to use quotes around the match string.

The annotation @EnabledIfEnvironmentVariable activates the test only when the environment variable named 'ENV' matches the given value. Here, 'test' is the correct match.

Complete the code to enable the test only if the environment variable 'MODE' matches 'debug'.

JUnit

@EnabledIfEnvironmentVariable(named = "MODE", matches = "[1]")
void debugTest() {
    // debug test code
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'Debug' instead of 'debug' (case mismatch).

Confusing 'MODE' with other environment variables.

The test runs only when the 'MODE' environment variable is set to 'debug'. This helps run debug-specific tests conditionally.

Fix the error in the annotation to enable the test only if the environment variable 'APP_ENV' equals 'production'.

JUnit

@EnabledIfEnvironmentVariable(named = "APP_ENV", matches = "[1]")
void productionTest() {
    // production test code
}

💡 Hint

Common Mistakes

Using uppercase or capitalized strings that do not match the environment variable.

Using shorthand like 'prod' instead of full 'production'.

The environment variable value is case-sensitive. 'production' in lowercase matches the expected value exactly.

Fill both blanks to enable the test only if the environment variable 'TEST_ENV' matches 'qa' and the method name is 'qaTest'.

JUnit

@EnabledIfEnvironmentVariable(named = "[1]", matches = "[2]")
void qaTest() {
    // QA environment test
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Swapping the environment variable name and value.

Using incorrect environment variable names.

The annotation checks that the environment variable named 'TEST_ENV' matches 'qa' to enable this test method.

5fill in blank

hard

Fill all three blanks to enable the test only if the environment variable 'BUILD_TYPE' matches 'nightly' and the method name is 'nightlyBuildTest'.

JUnit

@EnabledIfEnvironmentVariable(named = "[1]", matches = "[2]")
void [3]() {
    // Nightly build test
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using wrong environment variable names or values.

Mismatch between method name and the test purpose.

The test is enabled only when the 'BUILD_TYPE' environment variable equals 'nightly'. The method name must match 'nightlyBuildTest'.
