manage thread with junit4

Question

hello, with Junit4, i tried to write a test (.class) that contains 3 @test and need to open the appli in each test so in the function init that start the appli and close it : @BeforeClass public static void setupOnce() { final Thread thread = new Thread() {

public void run() {

//start the appli in the main

thread.start();

} } } @AfterClass public static void CloseAppli() {

closeAppli(); }

in my testClass : TestButtons.java I want to start the appli in each @test which is not possible... any idea ?
