groovy 在spock中模拟静态方法时偶尔会出错

我为同一个工具类方法编写了两个测试类（CryptUtilTest1.groovy、CryptUtilTest2.groovy），我模拟了CryptUtilTest2.groovy中的StringImplUtils.emptyIfBlank方法，当两个测试类分别执行时，测试类都能正常执行，但是当两个测试用例一起执行时，第二个测试类有时会出现如下错误：

> Task :CallServer:compileGroovy NO-SOURCE

Misplaced or misused argument matcher detected here:

-> at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:47)

You cannot use argument matchers outside of verification or stubbing.
Examples of correct usage of argument matchers:
    when(mock.get(anyInt())).thenReturn(null);
    doThrow(new RuntimeException()).when(mock).someVoidMethod(any());
    verify(mock).someMethod(contains("foo"))

This message may appear after an NullPointerException if the last matcher is returning an object 
like any() but the stubbed method signature expect a primitive argument, in this case,
use primitive alternatives.
    when(mock.get(any())); // bad use, will raise NPE
    when(mock.get(anyInt())); // correct usage use

Also, this error might show up because you use argument matchers with methods that cannot be mocked.
Following methods *cannot* be stubbed/verified: final/private/equals()/hashCode().
Mocking methods declared on non-public parent classes is not supported.

当按以下顺序一起执行测试时，我可以重现问题：

  1. CryptUtilTest1
  2. CryptUtilTest2
    如果在第一个测试中避免使用Mockito.anyString()，问题也会消失，因为第一个测试实际上并不是Mockito测试，该方法返回""，所以你可以在第一次测试中用""或者"dummy"来替换它，这样测试就通过了。s any*()方法旨在用于mockito匹配器表达式内部，例如类似verify(mock).someMethod(anyInt(), anyString(), eq("third argument"));的表达式。
