类名称：Assertions
方法名：assertThatCode

Assertions.assertThatCode介绍

[英]Allows to capture and then assert on a Throwable (easier done with lambdas).

The main difference with assertThatThrownBy(ThrowingCallable) is that this method does not fail if no exception was thrown.

Example :

ThrowingCallable boomCode = () -> { 
throw new Exception("boom!"); 
}; 
ThrowingCallable doNothing = () -> {}; 
// assertions succeed 
assertThatCode(doNothing).doesNotThrowAnyException(); 
assertThatCode(boomCode).isInstanceOf(Exception.class) 
.hasMessageContaining("boom"); 
// assertion fails 
assertThatCode(boomCode).doesNotThrowAnyException();

Contrary to assertThatThrownBy(ThrowingCallable) the test description provided with AbstractAssert#as(String,Object...) is always honored as shown below.

ThrowingCallable doNothing = () -> {}; 
// assertion fails and "display me" appears in the assertion error 
assertThatCode(doNothing).as("display me") 
.isInstanceOf(Exception.class);

This method was not named assertThat because the java compiler reported it ambiguous when used directly with a lambda :(
[中]允许捕获并在可丢弃文件上断言（使用lambdas更容易实现）。
与assertThatThrownBy（ThrowingCallable）的主要区别在于，如果没有引发异常，则此方法不会失败。
例子：

ThrowingCallable boomCode = () -> { 
throw new Exception("boom!"); 
}; 
ThrowingCallable doNothing = () -> {}; 
// assertions succeed 
assertThatCode(doNothing).doesNotThrowAnyException(); 
assertThatCode(boomCode).isInstanceOf(Exception.class) 
.hasMessageContaining("boom"); 
// assertion fails 
assertThatCode(boomCode).doesNotThrowAnyException();

与AbstractAssert#as（字符串、对象…）提供的测试描述assertThatThrownBy(ThrowingCallable)相反始终如下图所示

ThrowingCallable doNothing = () -> {}; 
// assertion fails and "display me" appears in the assertion error 
assertThatCode(doNothing).as("display me") 
.isInstanceOf(Exception.class);

此方法未命名为assertThat，因为java编译器在直接与lambda一起使用时报告它不明确：(
