[Dynamic configuration] [Playwright] Can't reconfigure configuration per scenario

在 dynamic-configuration/override-config.e2e-test.js 中运行复现，并将每个 Scenario 的 .config() 调用与正常工作的 Feature('Dynamic Configuration').config() 情况进行比较。跟踪 Scenario 配置如何传递到 Playwright helper，然后验证浏览器 override 对每个 Scenario 都生效，同时命令行 --override 的行为保持不变。

What are you trying to achieve?

What do you get instead?

Details

• CodeceptJS version: v3.0.4
• NodeJS Version: v12.18.3
• Operating System: macOS Catalina 10.15.7
• playwright
• Configuration file:

const { setHeadlessWhen } = require('@codeceptjs/configure');

// turn on headless mode when running with HEADLESS=true environment variable
// export HEADLESS=true && npx codeceptjs run
setHeadlessWhen(process.env.HEADLESS);

exports.config = {
  tests: '*/*.e2e-test.js',
  output: './output',
  helpers: {
    Playwright: {
      url: 'http://github.com',
      show: true,
      browser: 'chromium'
    }
  },
  include: {
    I: './steps_file.js'
  },
  bootstrap: null,
  mocha: {},
  name: 'experiments-with-codeceptjs',
  plugins: {
    pauseOnFail: {},
    retryFailedStep: {
      enabled: true
    },
    tryTo: {
      enabled: true
    },
    screenshotOnFail: {
      enabled: true
    }
  }
}

NOTE:

But it works for the Feature

Feature('Dynamic Configuration').config({"browser": "firefox"})

and I can override the configuration in runtime by using --override or -o option in the command line, passing valid JSON as a value:

codeceptjs run -o '{ "helpers": {"Playwright": {"browser": "firefox"}}}'
