测试报告优化要点

实际项目中需调整环境信息展示，优化用例描述显示，移除冗余列并控制日志输出。以下配置均在conftest.py中实现：

环境信息配置

from py.xml import html
import pytest

def pytest_configure(config):
    config._metadata["项目名称"] = "汽车钣喷应用测试"
    if "JAVA_HOME" in config._metadata:
        del config._metadata["JAVA_HOME"]
    if "Plugins" in config._metadata:
        del config._metadata["Plugins"]

@pytest.mark.optionalhook
def pytest_html_results_summary(prefix):
    prefix.append(html.p("测试团队: QA部门"))
    prefix.append(html.p("执行人员: 李明"))

用例描述与列调整

@pytest.mark.optionalhook
def pytest_html_results_table_header(cells):
    cells.insert(1, html.th('用例说明'))
    del cells[-1]

@pytest.mark.optionalhook
def pytest_html_results_table_row(report, cells):
    cells.insert(1, html.td(report.test_desc))
    del cells[-1]

@pytest.mark.hookwrapper
def pytest_runtest_makereport(item, call):
    outcome = yield
    result = outcome.get_result()
    result.test_desc = str(item.function.__doc__)

日志输出控制

@pytest.mark.optionalhook
def pytest_html_results_table_html(report, data):
    if report.passed:
        data.clear()
        data.append(html.div('用例执行成功', class_='log-info'))

失败截图功能

shared_values = {}

@pytest.fixture
def store_value():
    def _store(key, val):
        shared_values[key] = val
    return _store

@pytest.mark.hookwrapper
def pytest_runtest_makereport(item):
    pytest_html = item.config.pluginmanager.getplugin('html')
    outcome = yield
    test_report = outcome.get_result()
    extras = getattr(test_report, 'extra', [])
    
    if test_report.when in ('call', 'setup'):
        if test_report.failed:
            case_id = test_report.nodeid.replace("::", "_")
            img_data = capture_screenshot()
            if img_data:
                img_html = f'<div><img src="data:image/png;base64,{img_data}" style="width:600px;" /></div>'
                extras.append(pytest_html.extras.html(img_html))
        test_report.extra = extras

def capture_screenshot():
    return shared_values.get('driver').get_screenshot_as_base64()

测试统计收集

def pytest_terminal_summary(reporter, exitstatus, config):
    total_cases = reporter._numcollected
    passed = len([r for r in reporter.stats.get('passed', []) if r.when != 'teardown'])
    failed = len([r for r in reporter.stats.get('failed', []) if r.when != 'teardown'])
    pass_rate = f"{passed/total_cases*100:.2f}"
    
    duration = time.time() - reporter._sessionstarttime
    time_used = f"{duration:.2f}秒"
    
    stats_text = f"总用例: {total_cases} | 通过: {passed} | 失败: {failed} | 成功率: {pass_rate}% | 耗时: {time_used}"
    shared_values['test_stats'] = stats_text

应用示例

class TestUI:
    @pytest.fixture(autouse=True)
    def init_driver(self, store_value):
        driver = webdriver.Remote(
            command_executor='http://localhost:4723/wd/hub',
            options=webdriver.ChromeOptions()
        )
        store_value('driver', driver)

统计结果通过shared_values['test_stats']获取，可直接用于邮件通知：
