SetEnvironmentVariable and SetSystemProperty annotation cannot work in Junit 5

See original GitHub issue

I write below test case, but it cannot work. Please help check it.

@Test
@SetEnvironmentVariable(key = "abc", value = "123")
public void testHandleRequest() {
    // AlertAPIHandler apiHandler = new AlertAPIHandler();
    assertEquals("123", System.getenv("abc"));
}

@Test
@SetSystemProperty(key = "Test", value = "123")
public void testSystemProperty() {
    assertEquals("123", System.getProperty("Test"));
}

Below is my Gradle Settings:

testImplementation 'org.junit.jupiter:junit-jupiter-api:5.6.0'
testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.6.0'
testCompile group: 'org.junit-pioneer', name: 'junit-pioneer', version: '1.4.2'

Downgrading JUnit to 5.7.2 fixed the issue for me.

Running the following test:

class Issue508 {

	@Test
	@SetEnvironmentVariable(key = "env", value = "var")
	void testEnvVar() {
		assertEquals("var", System.getenv("env"));
	}

	@Test
	@SetSystemProperty(key = "sys", value = "prop")
	void testSysProp() {
		assertEquals("prop", System.getProperty("sys"));
	}

}

With the following build / Maven config:

<properties>
	<encoding>UTF-8</encoding>
	<project.build.sourceEncoding>${encoding}</project.build.sourceEncoding>
	<project.resources.sourceEncoding>${encoding}</project.resources.sourceEncoding>

I wasn’t able to reproduce the errors described above.

Therefore, I will close this issue. Feel free to reopen/comment if the problem pops up again.
