某个标签th:field="*{psNum}"显示error，如何解决

这种情况通常是因为表单提交的数据类型与后台接收的数据类型不匹配所导致的。你可以按照以下步骤进行排查和解决： ...<input type="text" th:field="*{psNum}" th:errors="${#fields.errors('psNum')}" />

def lastcase_result(self): result = self._outcome.result if result.failures: last_result = result.failures[-1] elif result.errors: last_result = result.errors[-1] else: last_result = None return last_result 执行时@unittest.skipIf(lastcase_result(),"last_testcase is failed") 报错

@unittest.skipIf()需要接受一个布尔类型的参数，但是lastcase_result()返回的是一个测试结果对象（比如TestResult）。你需要修改lastcase_result()方法，让它返回一个布尔值，表示最后一个测试用例是否失败...

def lastcase_result(): result = _outcome.result if result.failures: last_result = result.failures[-1] elif result.errors: last_result = result.errors[-1] else: last_result = None return last_result is not None
