If jumping out of a protected -// region, all .finally blocks are executed. -// .brtrue LABEL, (x) - Jump to a label IIF the expression `x` is truthy. -// If jumping out of a protected region, all .finally -// blocks are executed. -// .brfalse LABEL, (x) - Jump to a label IIF the expression `x` is falsey. -// If jumping out of a protected region, all .finally -// blocks are executed. -// .yield (x) - Yield the value of the optional expression `x`. -// Resume at the next label. -// .yieldstar (x) - Delegate yield to the value of the optional -// expression `x`. Resume at the next label. -// NOTE: `x` must be an Iterator, not an Iterable. -// .loop CONTINUE, BREAK - Marks the beginning of a loop. Any "continue" or -// "break" abrupt completions jump to the CONTINUE or -// BREAK labels, respectively. -// .endloop - Marks the end of a loop. -// .with (x) - Marks the beginning of a WithStatement block, using -// the supplied expression. -// .endwith - Marks the end of a WithStatement. -// .switch - Marks the beginning of a SwitchStatement. -// .endswitch - Marks the end of a SwitchStatement. -// .labeled NAME - Marks the beginning of a LabeledStatement with the -// supplied name. -// .endlabeled - Marks the end of a LabeledStatement. -// .try TRY, CATCH, FINALLY, END - Marks the beginning of a protected region, and the -// labels for each block. -// .catch (x) - Marks the beginning of a catch block. -// .finally - Marks the beginning of a finally block. -// .endfinally - Marks the end of a finally block. -// .endtry - Marks the end of a protected region. -// .throw (x) - Throws the value of the expression `x`. -// .return (x) - Returns the value of the expression `x`. -// -// In addition, the illustrative intermediate representation introduces some special -// variables: -// -// %sent% - Either returns the next value sent to the generator, -// returns the result of a delegated yield, or throws -// the exception sent to the generator. -// %error% - Returns the value of the current exception in a -// catch block. -// -// This intermediate representation is then compiled into JavaScript syntax.

To use this command, you need to first add a package that implements end-to-end testing capabilities. - -## Further help - -To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page. diff --git a/tests/legacy-cli/e2e/assets/12.0-project/angular.json b/tests/legacy-cli/e2e/assets/12.0-project/angular.json deleted file mode 100644 index 7c5d8e218668..000000000000 --- a/tests/legacy-cli/e2e/assets/12.0-project/angular.json +++ /dev/null @@ -1,118 +0,0 @@ -{ - "$schema": "./node_modules/@angular/cli/lib/config/schema.json", - "version": 1, - "newProjectRoot": "projects", - "projects": { - "twelve-project": { - "projectType": "application", - "schematics": { - "@schematics/angular:application": { - "strict": true - } - }, - "root": "", - "sourceRoot": "src", - "prefix": "app", - "architect": { - "build": { - "builder": "@angular-devkit/build-angular:browser", - "options": { - "outputPath": "dist/twelve-project", - "index": "src/index.html", - "main": "src/main.ts", - "polyfills": "src/polyfills.ts", - "tsConfig": "tsconfig.app.json", - "assets": [ - "src/favicon.ico", - "src/assets" - ], - "styles": [ - "src/styles.css" - ], - "scripts": [] - }, - "configurations": { - "production": { - "budgets": [ - { - "type": "initial", - "maximumWarning": "500kb", - "maximumError": "1mb" - }, - { - "type": "anyComponentStyle", - "maximumWarning": "2kb", - "maximumError": "4kb" - } - ], - "fileReplacements": [ - { - "replace": "src/environments/environment.ts", - "with": "src/environments/environment.prod.ts" - } - ], - "outputHashing": "all" - }, - "development": { - "buildOptimizer": false, - "optimization": false, - "vendorChunk": true, - "extractLicenses": false, - "sourceMap": true, - "namedChunks": true - } - }, - "defaultConfiguration": "production" - }, - "serve": { - "builder": "@angular-devkit/build-angular:dev-server", - "configurations": { - "production": { - "browserTarget": "twelve-project:build:production" - }, - "development": { - "browserTarget": "twelve-project:build:development" - } - }, - "defaultConfiguration": "development" - }, - "extract-i18n": { - "builder": "@angular-devkit/build-angular:extract-i18n", - "options": { - "browserTarget": "twelve-project:build" - } - }, - "e2e": { - "builder": "@angular-devkit/build-angular:protractor", - "options": { - "protractorConfig": "e2e/protractor.conf.js", - "devServerTarget": "twelve-project:serve" - }, - "configurations": { - "production": { - "devServerTarget": "twelve-project:serve:production" - } - } - }, - "test": { - "builder": "@angular-devkit/build-angular:karma", - "options": { - "main": "src/test.ts", - "polyfills": "src/polyfills.ts", - "tsConfig": "tsconfig.spec.json", - "karmaConfig": "karma.conf.js", - "assets": [ - "src/favicon.ico", - "src/assets" - ], - "styles": [ - "src/styles.css" - ], - "scripts": [] - } - } - } - } - }, - "defaultProject": "twelve-project" -} diff --git a/tests/legacy-cli/e2e/assets/12.0-project/e2e/protractor.conf.js b/tests/legacy-cli/e2e/assets/12.0-project/e2e/protractor.conf.js deleted file mode 100644 index f07dcd519768..000000000000 --- a/tests/legacy-cli/e2e/assets/12.0-project/e2e/protractor.conf.js +++ /dev/null @@ -1,36 +0,0 @@ -// @ts-check -// Protractor configuration file, see link for more information -// https://github.com/angular/protractor/blob/master/lib/config.ts - -const { SpecReporter, StacktraceOption } = require('jasmine-spec-reporter');
