ng e2e会构建，为应用程序提供服务，然后使用量角器运行端到端的测试用例。选项是可选参数。

争论

选件

Sr.No.	Option & Syntax	Description
1	–baseUrl=baseUrl	Base URL for protractor to connect to.
2	–configuration=configuration	A named build target, as specified in the “configurations” section of angular.json. Each named target is accompanied by a configuration of option defaults for that target. Setting this explicitly overrides the “–prod” flag Aliases: -c
3	–devServerTarget=devServerTarget	Dev server target to run tests against.
4	–grep=grep	Execute specs whose names match the pattern, which is internally compiled to a RegExp.
5	–help=true\|false\|json\|JSON	Shows a help message for this command in the console. Default: false
6	–host=host	Host to listen on.
7	–invertGrep=true\|false	Invert the selection specified by the ‘grep’ option. Default: false
8	–port	The port to use to serve the application.
9	–prod=true\|false	Shorthand for “–configuration=production”. When true, sets the build configuration to the production target. By default, the production target is set up in the workspace configuration such that all builds make use of bundling, limited tree-shaking, and also limited dead code elimination.
10	–protractorConfig=protractorConfig	The name of the Protractor configuration file.
11	–specs	Override specs in the protractor config.
12	–suite=suite	Override suite in the protractor config.
13	–webdriverUpdate=true\|false	Try to update webdriver. Default: true

首先转到使用ng build命令更新的角度项目。

现在运行e2e命令。

现在要修复故障，请更新app.component.html

app.component.html


   {{ title }} app is running!

现在运行e2e命令。
