Builder that generates HTML files from templates for dart tests.

test_html_builder #

A Dart builder that uses templates to generate HTML files for dart tests. Useful for projects with many tests that require custom HTML. Instead of having to replicate the custom HTML file for every test file that requires it, this builder can apply a template to any number of test files.

Usage #

Add this package as a dev_dependency:

dev_dependencies:
  test_html_builder: ^1.0.0

Create as many HTML test templates in the test/ directory as needed, e.g.:

<!-- test/example_template.html -->
<html>
    <head>
        <!-- Load custom assets needed by the test. -->
        <script src="custom.js"></script>

        <!--
        Every template must include this `{test}` token.
        It will be replaced by the builder with the required tags:
        <link rel="x-dart-test" href="...">
        <script src="packages/test/dart.js"></script>
        -->
        {test}
    </head>
</html>

Tell the builder which templates should be applied to which files, e.g.:

targets:
  $default:
    builders:
      test_html_builder:
        options:
          templates:
            "test/react_template.html":
              - "test/components/**_test.dart"
              - "test/react/**_test.dart"
            "test/default_template.html":
              - "test/**_test.dart"

Notes:

  • If there is overlap between the globs defined for multiple templates, the builder will choose the first template that matches.

  • If none of the templates match for a given test file, no html file will be generated.

  • One-off custom html files for individual tests are still supported, but they must use the .custom.html extension:

    • test/example_test.dart
    • test/example_test.custom.html

If you make changes to lib/src/config.dart and need to regenerate lib/src/config.g.dart:

  1. Uncomment the json_serializable: ^3.0.0 dev dependency in pubspec.yaml
  2. Comment out the entirety of build.yaml
  3. pub get && pub run build_runner build

This is necessary because a builder cannot depend on code that is generated by another builder in the same package. An alternative solution would be to define the TestHtmlBuilderConfig in a separate package, but this is simpler for now.
