Pytest插件

官方文档：API Reference — pytest documentation

BaseReport 定义Case结果输出

>>> from _pytest.reports import TestReport
>>> test = TestReport(1,1,1,'pass','','running')
>>> print(dir(test))

    # 获取常规的钩子方法的调用结果，返回一个result对象
    out = yield
 
    print('用例的执行结果', out)
 
    # 获取调用结果的测试报告，返回一个report对象，report对象的属性
    # 包括when(setup, call, teardown三个值)、nodeid(测试用例的名字)、
    # outcome(用例执行的结果 passed, failed)
    report = out.get_result()
 
    print('测试报告: %s' % report)
    print('步骤：%s' % report.when)

    # 打印函数注释信息
    print('description: %s' % str(item.function.__doc__))
    print('运行结果: %s' % report.outcome)

case运行不同步骤，重写pytest处理结果

 
    print('步骤：%s' % report.when)
    if when == "call":
       custom.running_test(item, call, report)
    if when == 'setup':
        custom.before_test(item, call, report)
    if when == 'teardown':
        custom.after_test(item, call, report)

获取case运行时失败信息

    excinfo = call.excinfo
    trace_info = traceback.format_exception(excinfo.type, excinfo.value, excinfo.tb    )

获取case运行时失败信息

    report = out.get_result()
    print('测试报告Case日志: %s' % report.caplog())
    print('测试报告Case stderr: %s' % report.capstderr())
    print('测试报告Case stdout: %s' % report.capstdout())
