    The `TestBed` API consists of static class methods that either update or reference a _global_ instance of the`TestBed`.
  
    `TestBed`的API包含了一系列静态类方法，它们更新或者引用**全局**的`TestBed`实例。
    
    Internally, all static methods cover methods of the current runtime `TestBed` instance that is also returned by the `getTestBed()` function.
  
    在内部，所有静态方法在`getTestBed()`函数返回的当前运行时间的`TestBed`实例上都有对应的方法。
  
    Call `TestBed` methods _within_ a `BeforeEach()` to ensure a fresh start before each individual test.
  
    在`BeforeEach()`内调用`TestBed`方法，这样确保在运行每个单独测试时，都有崭新的开始。
  
    Here are the most important static methods, in order of likely utility.
