i am trying to create a testsuite for an application wherein I have created an abstract class as Test, which has an abstract method ExecuteTest()

This(abstract class Test) is extended by various tests to and ExecuteTest Is overridden to desired test

Now the issue is, i have numerous tests, which I feel can be combined.

The code looks like:
abstract class Test
{
public abstract ExecuteTest()
}

class TestScenario1:Test
{
override ExecuteTest()
{
common part A
code for test scenario 1
common part B

class a {
  method1(String s) {
    //Do Stuff
  }

  method2(String s) {
    //Do other stuff
  }
}

class testA {

  @before
  setup() {
    // Setup your test somehow
  }

  @after
  cleanup() {
    // Clean up the mess your test made
  }

  @test
  testMethod1() {
    // Make sure this method works!
  }

  @test
  testMethod2(){
    // Make sure this method works!
  }

}

class a {
  login(String s) {
    //Do Stuff
  }

  clickButtonOne(String s) {
    //Do other stuff
  }
}

class testA {

  @before
  setup() {
    // Setup your test somehow
  }

  @after
  cleanup() {
    // Clean up the mess your test made
  }

  @test
  testOne() {
    // Make sure this method works!
    startPerfTimer()
    login()
    stopPerfTimer()
    startPerfTimer()
    clickButtonOne()
    stopPerfTimer()
    // Do other stuff
  }

  startPerfTimer() {

  }

  stopPerfTimer() {

  }

class testLogin {

  Server s;

  @before
  setup() {
    // Initialize your server
    s = new Server();
  }

  @after
  cleanup() {
    // Delete your previous server
    s = null;
  }

  @test
  testFreshServer() {
    startPerfTimer()
    login()
    stopPerfTimer()
  }

  testNotFreshServer() {
    login()
    logout()
    startPerfTimer()
    login()
    stopPerfTimer()
  }

}

class testButtonOne {

  Server s;

  @before
  setup() {
    s = new server()
    // We no longer care about the performance of login! It's already tested and measured!
