如何在 Alpine Docker 容器上运行 Playwright 浏览器测试？

Question

Playwright 附带的 Java 驱动程序不适用于 Alpine，因为它们不使用静态链接的 MUSL 构建。

Answer 1

在您的 Alpine 映像中，从 Alpine 存储库安装nodejs并chromium设置环境变量，告诉 Playwright 使用它们而不是自己的驱动程序：

echo "https://dl-cdn.alpinelinux.org/alpine/edge/main" > /etc/apk/repositories \
    && echo "https://dl-cdn.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories \
    && echo "https://dl-cdn.alpinelinux.org/alpine/edge/testing" >> /etc/apk/repositories \
    && echo "https://dl-cdn.alpinelinux.org/alpine/v3.16/main" >> /etc/apk/repositories \
    && echo "https://dl-cdn.alpinelinux.org/alpine/v3.16/community" \
    && apk upgrade -U -a \
    && apk add \
    libstdc++ \
    chromium \
    harfbuzz \
    nss \
    freetype \
    ttf-freefont \
    font-noto-emoji \
    wqy-zenhei \
    nodejs \
    && rm -rf /var/cache/* \
    && mkdir /var/cache/apk

export PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1
export PLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH=/usr/bin/chromium-browser
export PLAYWRIGHT_NODEJS_PATH=/usr/bin/node

然后，在 Java 或 Kotlin 代码中，您必须自己处理自定义浏览器位置：

abstract class AbstractBrowserTest(private val headless: Boolean = true) {

    private val playwright: Playwright = Playwright.create()
    private val browser: Browser = launchBrowser()

    private fun launchBrowser(): Browser {
        val env = System.getenv("PLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH")
        return if (env != null && env.isNotBlank()) {
            playwright.chromium().launch(LaunchOptions().setHeadless(true).setExecutablePath(Paths.get(env)))
        } else {
            playwright.chromium().launch(LaunchOptions().setHeadless(headless))
        }
    }
}
