순차적 thread

요소를 찾고 있는 중에 다른 요소를 찾는 과정이 실행되면 안되므로 thread에 lock을 걸어줬다.
버튼을 누르면 함수가 쓰레드로 실행되게 했다.

``` python
lock = threading.Lock() # lock 객체 생성

def basic_test_lock(self): 
        lock.acquire()  # lock
        try: 
            self.result_label.config(text="기본 도구 테스트 진행중") 
            basic_test(self.version_result_label["text"]) 
        finally: 
            lock.release() # lock해제 - 다른 쓰레드가 실행가능
            self.result_label.config(text="기본 도구 테스트 끝")
            
basicBtn=Button(window, text="기본",height = 2,  width = 7,  command = threading.Thread(target=self.basic_test_lock).start)  
        
```
