测试

def "为null测试"() {
    given:
    IsBlankEntity entity = new IsBlankEntity().setName(name)

    expect:
    boolean actResult = MkValidators.check(entity, "name")
    if (!actResult) {
         println MkValidators.getErrMsg()
         println MkValidators.getErrMsgChain()
    }
    Assert.assertEquals(result, actResult)

    where:
    name | result
    "a"  | false
    null | true
    null | true
    ""   | true
    "a"  | false
