Explanation is very much particular ...its good for beginners, post more videos for live example(demo project) to cover all scenarios. Big thanks for your time and also explanation.
Yor are awesome!!! Your videos are becoming my javascript guide and it's helping me to learn things with ease and completely understandable. Keep rocking!!
Thank you for the simple explaination. Could you please also dig deeper into testing demonstrating complex functionalities aswell on the latest angular (angular9)?
Hi Can you please upload more regarding this topic like with components, mocking and spies. Above one is so simple and clear to understand or suggest where to refer as such.
Thanks for the video. Why do we need to run karma on Firefox? I mean it only launch the browser just to show the report of the tests. I think with Chrome launcher is enough. What do you think? Thanks
Its because how browser implements JavaScript. there are cases where some function works little differently on Firefox than Chrome. So just to get good coverage.
Hi, nice tutorial! Could you please continue the topic with more advanced testing? I recently struggled with writing tests for HTTP requests (configuring testbed and mocking responses). Also, things get complicated when you have to test component methods that use methods from a service.
Yes, I will continue with the unit testing tutorials on component testing, mocking, e2e testing and such. It might be in a month as i have a vacation coming up.
Hi, Am trying to write test for input fields and some of the HTML components if I write test case for this it's working fine but when in inject any services inside my component and try to write test case for same input and HTML components it's not rendering in spec file and am getting error like "object prototype may only be an object or null:undefined" if you have any idea about how to resolve it please let me know
Great work! Can you make more videos with little bit of bigger scope automation? like Manual test integration, integration testing, actionwords from cucumber, async(), .
This is very nice. Thank you. Could you please make a video for complete testing of a component which has input/output and directives. Also the API call. Thanks.
Hi , It was an amazing video on unit testing, however i am a tester and want to do unit testing with the help of my developer. I am very new to angular , what are the requirements for me to know and work on unit testing, how to start off?
i would suggest. use unit tests to test individual functions only. Depending on how big the project is and use e2e tests to do more. Are you familiar with e2e tests in angular?
techsith the project just kicked off , so developers are busy coding . I have started my bit of research and learning from the videos. I have installed all the prerequisites for unit and e2e and slowly progressing. I was thinking first let me see if I can do unit test, that would give me an idea about the functions used. Can u provide me your mail id, i would like to discuss about learnings.
I have one more video on unit testing th-cam.com/video/WROmnhRbH6k/w-d-xo.html will make more also i have a larger series on angular th-cam.com/play/PL7pEw9n3GkoWoDfLSOQCtLIEg-gL5dYOF.html
Hi , it's very informative and it's help me to understand the testing. Thanks a lot for Tutorial Quick question: How to perform testing on OTP or soft token. Please me with your inputs.
This was good. But I didnt see any integration of Protractor. You are running everything through A. CLI using Karma. Also, Protractor is End to end testing tool then how can you use it in Unit testing. Very confused with this. Little enlightment would be awesome.
I totally get that testing as a practice is a good idea. However I still don't understand this unit testing thing: I mean, if you're SO thorough as to set up tests for everything, then aren't the tests themselves becoming a bit redundant?
Eros, unit testing is actually very important. Especially, in a team environment. Think of this way where you made sure as a developer your part, and someone else changes either your code or the code your code depends on . you won't see if something is breaking until its too late. Having passing unit test means nothing is broken. So if you work in a team environment without unit testing, you will suffer a lot. Most of the companies require you to write tests for every function.
I had Interview on angular 2 could not answers 3 questions please help we with this 1) why do we use Services in angular2 2) how MVC work in angular2? 3) can we use reactJS in angular2?
1) Functionalities that you want to use at many components in Angular should be inject into those components. This way you get the code usability. 2) Angular2 is component base architecture so classical MVC doesnt really work. so you should not be using it. 3) Angular 2 has an optional hook, onInit(), that takes advantage of triggering the code to render a React component
1)why do we use services & how do you inject a service into a component? 2)what is a router? (go through all the concept) 3)what are directive & how do you use a custom directive? 4)what are pipes & how do you use a custom pipe? 5)how do you validate forms & how Authentication works in login page? 6)how do you communicate from one component to another component? 7)what is Data binding? 8)what is event emitter? 9) what is Module and how inheritance works in angular 2? 10)what is the use of typescript in angular2? 11)life cycle hooks of angular2? 12)b/w Observables and promise? 13)what is ng-template? 14)what is the use of constructor in Angular? 15)how do you perform Unit testing in Angular? 16)what is lazy loading, view child, content child & decorator? 17)how does angular app starts? 18)how do you make Http request? All the best for your interview

you would have to mock the input here
@@Techsithtube can you share one example
How do i run particular service or component test file instead of running all the files?. Pls explain how do i configure in karma. config. Js
you can run the grep by filename using following command karma run -- --grep=filename
Nice introduction. Thank you!
Thanks for the video. Why do we need to run karma on Firefox? I mean it only launch the browser just to show the report of the tests. I think with Chrome launcher is enough. What do you think? Thanks
Its because how browser implements JavaScript. there are cases where some function works little differently on Firefox than Chrome. So just to get good coverage.
Thats simple and nice session. Thank you for the video.
Very nice video - is there one on testing POST services ?
Hi, nice tutorial! Could you please continue the topic with more advanced testing? I recently struggled with writing tests for HTTP requests (configuring testbed and mocking responses). Also, things get complicated when you have to test component methods that use methods from a service.
Yes, I will continue with the unit testing tutorials on component testing, mocking, e2e testing and such. It might be in a month as i have a vacation coming up.
That's great, thank you! Have a nice vacation :)
Hello. I'm doing a university project and I need mocking and e2e testing tutorial. I am wondering if you are gonna do it any time soon?
I will make e2e testing tutoiral next week
Oh, that's great! Thanks a lot :)

Is it a data service?
techsith yes we are using data service
you would need to mock the data.
really nice tutorial.easy to understand.pls do more unit test videos.thanks a lot.
Yes I will do some more on over all unit tests and e2e tests
Great work! Can you make more videos with little bit of bigger scope automation? like Manual test integration, integration testing, actionwords from cucumber, async(), .
Thank you for the tutorial! It would be better if we can have another tutorial on how to test the functions, how to test observable subscriber method.
It was a nice tutorial, got the unit test scenario
Thanks a lot for the "fdescribe" and "xdescribe" trick
Hi Sir,

Hello Sir.. Really nice explanation. Could you please make a video on unit testing in react (with Jest) as well ?
I do have a plan for jest tutorials. will make them soon.
Awesome! Thank you!
Very helpful, thanks!
Thank You Very Much.. Sir..
Thanks for watching Rangarao.
Nice explanation
Superb... Nice tutorial
Please write test on the API and primeng forms in angular
we can remove code duplicate by creating service object in beforeEach()
That is true. :)
Right to the point
very helpful
Hi,
One of the most easiest tutorial to setup test framework with angular Js. Could you provide the same for react JS too
Sure I am going to extend the react series further. And include tests as well.
right to the point
