This is a prerequisite to fix a bug in template completions whereby completion of the string `ti` for the variable `title` results in `tititle`. This is because the position where the completion is requested is used to insert the completion text. This is incorrect. Instead, a `replacementSpan` should be used to indicate the span of text that needs to be replaced. Angular's own `Completion` interface is insufficient to hold this information. Instead, we should just use ts.CompletionEntry. Also added string enum for `CompletionKind`, which is similar to ts.ScriptElementKind but contains more info about HTML entities. PR Close #32375
Integration tests for Angular
This directory contains end-to-end tests for Angular. Each directory is a self-contained application that exactly mimics how a user might expect Angular to work, so they allow high-fidelity reproductions of real-world issues.
For this to work, we first build the Angular distribution just like we would publish it to npm, then install the distribution into each app.
To test Angular CLI applications, we use the integration test cli-hello-world.
When a significant change is released in the CLI, the application should be updated with ng update:
$ cd integration/cli-hello-world
$ yarn install
$ yarn ng update @angular/cli @angular-devkit/build-angular
# yarn build
# yarn test
# typescript version
Render3 tests
The directory cli-hello-world-ivy-compat contains a test for render3 used with the angular cli.
The cli-hello-world-ivy-minimal contains a minimal ivy app that is meant to mimic the bazel
equivalent in packages/core/test/bundling/hello_world, and should be kept similar.
Writing an integration test
The API for each test is:
- Each sub-directory here is an integration test
- Each test should have a
package.jsonfile - The test runner will run
yarnandyarn teston the package
This means that the test should be started by test script, like
"scripts": {"test": "runProgramA && assertResultIsGood"}
Note that the package.json file uses a special file://../../dist scheme
to reference the Angular packages, so that the locally-built Angular
is installed into the test app.
Also, beware of floating (non-locked) dependencies. If in doubt
you can install the package directly from file:../../node_modules.
Running integration tests
$ ./integration/run_tests.sh
The test runner will first re-build any stale npm packages, then cd into each
subdirectory to execute the test.
