如何动态修改protractor-html-screenshot-reporter的测试结果文件夹路径？

Got it, let's walk through practical ways to dynamically set the results directory for your protractor-jasmine2-screenshot-reporter setup, using your existing conf.js as a starting point. Here are three common, flexible approaches:

1. Pass the Path via Command-Line Parameters #

This lets you specify a custom folder every time you run your tests, which is great for ad-hoc runs or targeting different output locations.

First, update your conf.js to accept a parameter with a default fallback:

var HtmlScreenshotReporter = require('protractor-jasmine2-screenshot-reporter');

exports.config = {
  // Define a default results directory (used if no param is passed)
  params: {
    resultsDir: '/opt/src/protractor/results/'
  },
  // ... rest of your existing config options

  beforeLaunch: function() {
    // Initialize the reporter with the dynamic path from params
    var reporter = new HtmlScreenshotReporter({
      dest: exports.config.params.resultsDir,
      filename : 'index.html',
      showSummary : true,
      showQuickLinks : true,
      showConfiguration : true,
      cleanDestination : true,
      ignoreSkippedSpecs : false,
      reportOnlyFailedSpecs : false,
      captureOnlyFailedSpecs : true,
    });

    // Don't forget to add the reporter to Jasmine (assuming you had this logic)
    jasmine.getEnv().addReporter(reporter);
  },
  // ... remaining config code
};

Then run your tests with the custom path like this:

protractor conf.js --params.resultsDir=/opt/src/protractor/my-custom-results/

2. Generate a Timestamped Folder (Auto-Archiving) #

If you want to avoid overwriting previous test results (great for debugging or tracking runs over time), generate a unique folder with a timestamp each time tests run.

Modify your conf.js like this:

var HtmlScreenshotReporter = require('protractor-jasmine2-screenshot-reporter');

// Create a unique directory name using a timestamp (replace invalid chars)
const timestamp = new Date().toISOString().replace(/[:.]/g, '-');
const dynamicResultsDir = `/opt/src/protractor/results-${timestamp}/`;

var reporter = new HtmlScreenshotReporter({
  dest: dynamicResultsDir,
  filename : 'index.html',
  showSummary : true,
  showQuickLinks : true,
  showConfiguration : true,
  cleanDestination : true,
  ignoreSkippedSpecs : false,
  reportOnlyFailedSpecs : false,
  captureOnlyFailedSpecs : true,
});

exports.config = {
  // ... your existing config

  beforeLaunch: function() {
    jasmine.getEnv().addReporter(reporter);
  },
  // ... rest of config
};

Now every test run will create a folder like results-2024-05-20T14-30-00-123Z/, keeping all results separate.

3. Use Environment Variables (Great for CI/CD) #

If you're running tests in a CI/CD pipeline or want to set the path globally for your environment, use an environment variable with a default fallback.

Update your conf.js:

var HtmlScreenshotReporter = require('protractor-jasmine2-screenshot-reporter');

// Use the environment variable if set, else fall back to the default path
const resultsDir = process.env.PROTRACTOR_RESULTS_DIR || '/opt/src/protractor/results/';

var reporter = new HtmlScreenshotReporter({
  dest: resultsDir,
  // ... other reporter options
});

exports.config = {
  // ... your existing config

  beforeLaunch: function() {
    jasmine.getEnv().addReporter(reporter);
  },
  // ... rest of config
};

Then set the environment variable before running your tests:

# Linux/macOS
export PROTRACTOR_RESULTS_DIR=/opt/src/protractor/ci-results/
protractor conf.js

# Windows (Command Prompt)
set PROTRACTOR_RESULTS_DIR=C:\src\protractor\ci-results\
protractor conf.js

Pick the approach that best fits your workflow—command-line params for manual control, timestamps for auto-archiving, or environment variables for CI environments.
