使用 Visual Studio Code 进行 JUnit 测试中的路径问题

Question

I'm experiencing some problems with generating tests containing absolute paths with JUnit in VSC.

The following two variables writtenFilePath and generatedFilePath both contain the same identical String when I print them in the terminal. However they produce different outcomes when used in a JUnit test.

private String writtenFilePath = "/home/$USER/Desktop/S2/src/test/test1.in";
private String generatedFilePath = Paths.get("").toAbsolutePath().toString().concat("/src/test/test1.in");

writtenFilePath produces the desired outcome when used in a test while generatedFilePath does not as the test cannot access the file.

Below is the error prompt from the following JUnit test, testing that the two Path Strings are equal.

@Test
public void identicalFilePathsAreEqual() {
    assertEquals(writtenFilePath,generatedFilePath);
}

**org.junit.ComparisonFailure:**

**expected:**
/home/$USER/[Desktop/S]2/src/test/test1.in

**but was:**
/home/$USER/[.config/Code/User/workspaceStorage/c1a1302e27095d0a416037f60c4e3677/redhat.java/jdt_ws/S2_a43208c]2/src/test/test1.in

The test I'm trying to run: (Works as intended with the writtenFilePath, fails with the generatedFilePath)

@Test
public void sizeIsSixFromTest1() throws IOException {
    System.setIn(new ByteArrayInputStream(readLineByLineJava8(generatedFilePath).getBytes()));
    Lexer lex = new Lexer(System.in);
    assertEquals(6,lex.howManyTokens());
}

Visit https://code.visualstudio.com/docs/java/java-testing

Customize test configurations

search in preferences in VSC for java.test.config

open settings.json

set workspacefolder with

"java.test.config": {
"workingDirectory": "${workspaceFolder}"
}

then it should work... had the same issue yesterday and found this solution today... and it works;)
