pytest_terminal_summary 关于TerminalReporter…前言 用例执行完成后我们希望能获取到执行的结果这样方便我们快速统计用例的执行情况。 也可以把获取到的结果当成总结报告发邮件的时候可以先统计测试结果再加上html的报告。
pytest_terminal_summary 关于TerminalReporter类可以在_pytest.terminal中查看到 pytest_terminal_summary(terminalreporter, exitstatus, config)
最后的结果汇总,可以拿到所有的执行结果
参数
- terminalreporter (_pytest.terminal.TerminalReporter) – 内部使用的终端测试报告对象
- exitstatus (int) – 返回给操作系统的返回码
- config(_pytest.config.Config) - pytest config对象
TerminalReporter部分代码

案例参考
先在test_a.py写几个用例
# test_a.py
import pytest
# 上海-悠悠def test_1():print(测试用例1111)assert 1 1pytest.mark.skip(跳过)
def test_2():print(测试用例22222)assert 1 1def test_3():print(测试用例3333)def test_4():print(测试用例44444444)assert 1 2
test_b.py用例参考
# test_b.py
import time
# 上海-悠悠def test_5():print(测试用例55555555)time.sleep(3)def test_6():print(测试用例66666666)time.sleep(3)assert 1 2
于是在conftest.py中写个 pytest_terminal_summary 函数收集测试结果
import time
# 上海-悠悠def pytest_terminal_summary(terminalreporter, exitstatus, config):收集测试结果print(terminalreporter.stats)print(total:, terminalreporter._numcollected)print(passed:, len(terminalreporter.stats.get(passed, [])))print(failed:, len(terminalreporter.stats.get(failed, [])))print(error:, len(terminalreporter.stats.get(error, [])))print(skipped:, len(terminalreporter.stats.get(skipped, [])))# terminalreporter._sessionstarttime 会话开始时间duration time.time() - terminalreporter._sessionstarttimeprint(total times:, duration, seconds)

setup和teardown异常情况
如果setup出现异常test_b.py代码修改下
# test_b.py
import time
import pytest
# 上海-悠悠pytest.fixture(scopefunction)
def setup_demo():raise TypeError(ERROR!)def test_5(setup_demo):print(测试用例55555555)time.sleep(3)def test_6():print(测试用例66666666)time.sleep(3)assert 1 2
重新运行用例,结果如下
total: 6
passed: 2
failed: 2
error: 1
skipped: 1
成功率33.33%
total times: 3.1817877292633057 seconds2 failed, 2 passed, 1 skipped, 1 error in 3.18 seconds
此时统计结果没什么问题接下来看teardown异常情况
# test_b.py
import time
import pytest
# 上海-悠悠pytest.fixture(scopefunction)
def setup_demo():yield raise TypeError(ERROR!)def test_5(setup_demo):print(测试用例55555555)time.sleep(3)def test_6():print(测试用例66666666)time.sleep(3)assert 1 2
运行结果

skipped: 1
成功率50.00%
total times: 6.18759298324585 seconds2 failed, 3 passed, 1 skipped, 1 error in 6.19 seconds
这个时候总用例是6但是2 failed, 3 passed, 1 skipped, 1 error加起来的个数是7这个为什么
从 terminalreporter.stats 可以看出 passed 里面 whencall 时候统计了一次 test_5 用例
TestReport test_b.py::test_5 whencall outcomepassederror 里面 whenteardown 又统计了一次 test_5 用例
error: [TestReport test_b.py::test_5 whenteardown outcomefailed]whenteardown 是测试用例的后置操作一般用于数据的清理报错了的话不影响测试用例的执行结果所以可以忽略掉
修改后的最终代码如下
import time
# 上海-悠悠def pytest_terminal_summary(terminalreporter, exitstatus, config):收集测试结果# print(terminalreporter.stats)print(total:, terminalreporter._numcollected)print(passed:, len([i for i in terminalreporter.stats.get(passed, []) if i.when ! teardown]))print(failed:, len([i for i in terminalreporter.stats.get(failed, []) if i.when ! teardown]))print(error:, len([i for i in terminalreporter.stats.get(error, []) if i.when ! teardown]))print(skipped:, len([i for i in terminalreporter.stats.get(skipped, []) if i.when ! teardown]))print(成功率%.2f % (len(terminalreporter.stats.get(passed, []))/terminalreporter._numcollected*100)%)# terminalreporter._sessionstarttime 会话开始时间duration time.time() - terminalreporter._sessionstarttimeprint(total times:, duration, seconds)
运行后的结果
total: 6
passed: 3
failed: 2
error: 0
skipped: 1
成功率50.00%
total times: 6.20133113861084 seconds2 failed, 3 passed, 1 skipped, 1 error in 6.20 seconds
拿到测试结果
很多小伙伴问到如何拿到测试结果这里我把测试结果保存为txt文件你们也可以保存json文件
