【问题描述】：

我正在尝试使用 java 运行我的第一个 Playwright 跟踪，但我遇到了错误，我不确定我错过了什么，我正在 Intlij 中运行 mu 代码

Playwright playwright = Playwright.create();
        Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setHeadless(false));
        BrowserContext browserContext = browser.newContext();
        browserContext.tracing().start(new Tracing.StartOptions().setScreenshots(true).setSnapshots(true).setSources(true));
        Page page = browser.newPage();
        page.navigate("https://www.saucedemo.com/");

我遇到了错误

【解决方案1】：

为了让 Playwright 将您的测试源链接到跟踪日志，它需要知道源文件夹的位置，如文档 here 中所述。

例如在 Powershell 中你可以这样设置：

$env:PLAYWRIGHT_JAVA_SRC="src/test/java"

这会将源添加到跟踪和检查器中。

如果您不需要源，您可以在创建上下文实例时禁用它：

context.tracing().start(new Tracing.StartOptions()
       .setScreenshots(true)
       .setSnapshots(true)
       .setSources(false));
