public Form1()
    {
        InitializeComponent();
        Collection<Test> tests = new Collection<Test>();
        tests.Add(new Test("test1"));
        tests.Add(new Test("test2"));
        foreach (Test test in tests)
        {
            Button button = new Button();
            button.Text = test.name;
            button.Click+=new EventHandler((object obj, EventArgs arg)=>{
                this.CreateTest(test);
            });
            this.flowLayoutPanel1.Controls.Add(button);
        }
