groovy - JMeter 断言结果

Question

我正在运行 JSR223 断言，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，因为我在日志中收到内部错误。
这是我的断言结果。
Assertion Results
这是日志

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

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:假”和“断言失败:真”。

你能帮我理解我在哪里犯了错误。我最担心的是日志中的错误。谢谢!

这是发生了什么:

您正在使用 Groovy“断言”。如下比较是错误的:

expected_response != actual_response

你最终失败了:

assert set_assertion == true;

这会抛出 org.codehaus.groovy.runtime.powerassert.PowerAssertionError 这是一个子类或 java.lang.Error 被困在这里:

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

所以 JMeter 执行这段代码，这就是你得到的:

        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");
 }
