Serenity-js: Support for serenity-js with typescript 2.4.2 version

[codesandtags]

Currently, I'm using in serenity-js in a project and we had to upgrade the angular version to 5.2.0, but after that, it has some issues with the typescript version when I run the e2e test.

This is an example of the error that I get using typescript 2.4.2 and running the e2e test.

info: Serenity BDD CLI jar file is up to date :-)

After reviewing the issue with the versions, I've decided to update in my project the typescript version to 2.4.0 and finally, the e2e tests are running, however, I'm getting a warning message when I build the project using angular-cli.

@angular/[email protected] requires typescript@'>=2.4.2 <2.5.0' but 2.4.0 was found instead.
Using this version can result in undefined behaviour and difficult to debug problems.

Please run the following command to install a compatible version of TypeScript.

    npm install typescript@'>=2.4.2 <2.5.0'

To disable this warning run "ng set warnings.typescriptMismatch=false".

Is possible for this project, add compatibility to support at least the typescript 2.4.2 version in order to avoid the warning with angular 5 projects?

Thanks in advance,

Edwin Torres.

Thanks for reporting that, Edwin! The newer versions of TypeScript are a bit more strict on generics. SerenityBDDReporter needs to be improved so support those new rules. I'm planning to work on this shortly.

Thanks,

Thanks @jan-molak I'll be waiting for that.

Cheers and happy coding.

Is there any progress on this issue? I am having the same issue.

Thanks.

@azimmalik - Serenity/JS v2 is transpiled using TypeScript 3.6. Since version 2 is going to supersede v1, the best way forward will be to upgrade to v2.

There's an example project available at https://github.com/serenity-js/serenity-js-cucumber-protractor-template and I'm working on documentation and an "official" release of v2 (currently in stable alpha) as we speak.

Hope this helps!
Jan
