What did you do?

I tried to delete a directory and it failed to delete in a unit test while returning no error

func Test_AddNewUser(t *testing.T) {

ConfigurationFile.UsersDirectory = "./UserResults"
newUser := "Dracula Bramstokers"
newFile := ConfigurationFile.UsersDirectory + PS + "Dracula_Bramstokers.json"
err := AddNewUser(newUser)
assert.Nil(t, err, "This should be nil")
assert.FileExists(t, newFile, "File should have been created")
os.Remove(newFile)

ConfigurationFile.UsersDirectory = "bluhbluh"

newUser = "Dracula Bramstokers"
newFile = ConfigurationFile.UsersDirectory + PS + "Dracula_Bramstokers.json"
err = AddNewUser(newUser)
assert.Nil(t, err, "This should be nil")
assert.FileExists(t, newFile, "File should have been created")
os.RemoveAll("bluhbluh")

}

func Test_ListOfUserResultPaths(t *testing.T) { ConfigurationFile.UsersDirectory = "UnitTestingUsers" newUserOne := "Dracula Vampire" newUserTwo := "Werewolf Wolfie" newUserThree := "Flying Monkey" newFileOne := ConfigurationFile.UsersDirectory + PS + newUserOne newFileTwo := ConfigurationFile.UsersDirectory + PS + newUserTwo newFileThree := ConfigurationFile.UsersDirectory + PS + newUserThree

errOne := AddNewUser(newUserOne)
errTwo := AddNewUser(newUserTwo)
errThree := AddNewUser(newUserThree)

assert.Nil(t, errOne)
assert.Nil(t, errTwo)
assert.Nil(t, errThree)

assert.Contains(t, newFileOne, newUserOne)
assert.Contains(t, newFileTwo, newUserTwo)
assert.Contains(t, newFileThree, newUserThree)

listOfUserResultPaths := ListOfUserResultPaths()
assert.Contains(t, listOfUserResultPaths[0], "Dracula")
assert.Contains(t, listOfUserResultPaths[1], "Monkey")
assert.Contains(t, listOfUserResultPaths[2], "Werewolf")
assert.Len(t, listOfUserResultPaths, 3)

os.RemoveAll(ConfigurationFile.UsersDirectory)

}

The second one did not remove the dir

What did you expect to see?

I expected to see the directory removed or an error reporting why it did not

What did you see instead?

I saw the directory remain
