Question

我正在运行JSR223 Assertion，我使用groovy将预期响应与实际响应进行比较。如果它们不相等，则断言失败。这是代码

import groovy.json.JsonSlurper;

JsonSlurper slurper = new JsonSlurper();
boolean set_assertion = true;

def expected_response = slurper.parseText("<JSON response goes here>");
def actual_response = slurper.parseText(prev.getResponseDataAsString());

if (expected_response != actual_response)
{
    set_assertion = false;
    log.error("expected_response != actual_response");
    assert set_assertion == true;
    SampleResult.setSuccessful(false);  
}

现在，断言确实失败了。但我认为它失败了，因为我在日志中出现内部错误。这是我的断言结果。 Assertion Results 这是日志

ERROR - jmeter.threads.JMeterThread: Error processing Assertion  Assertion failed: 

assert set_assertion == true
       |             |

理想情况下，我不应该有错误，我的断言应该失败并且应该有以下结果'断言错误：错误'和'断言失败：真'。

你能帮我理解我犯错的地方吗？我最担心的是日志中的错误。谢谢！

以下是发生的事情：

你正在使用Groovy“断言”。如下所示，比较是错误的：

expected_response！= actual_response

你最终失败了：

断言set_assertion == true;

抛出org.codehaus.groovy.runtime.powerassert.PowerAssertionError，它是一个子类或java.lang.Error，它被困在这里：

https://github.com/apache/jmeter/blob/trunk/src/core/org/apache/jmeter/threads/JMeterThread.java#L771

所以JMeter执行这个代码就是你得到的：

        assertionResult = new AssertionResult("Assertion failed! See log file.");
        assertionResult.setError(true);
        assertionResult.setFailureMessage(e.toString());

这对我来说似乎很好，但为什么在这里使用Groovy断言？这样做会更有效率：

 if ( expected_response != actual_response )
 {
      log.error("expected_response != actual_response");
      AssertionResult.setFailure(true);
      AssertionResult.setFailureMessage("expected_response != actual_response");
 }
