This is a great tutorial, I wanted to dive deeper and bought your course on Udemy - there is so much more on the Unit Testing topic. I heartily recommend it to all interested! (great deal by using the link in the description). You're a great teacher Mosh!
I very liked that at the beginning you clarify, why someone would need automated tests and why someone would not need them. That's pretty true and I think you could copy that part in a separate video and release that. That has nothing to do with Angular, so others may find that part interesting too.
This video was extremely helpful for me to understand the fundamentals of testing, which I was quite unfamiliar with. Now as I have a basic understanding, I can move on to the advanced concepts of tests. Thanks Mosh, for bring out this tutorial for us.
That's one hell of an intro abouth this subject. Congrats. I come from Java where we write tests before code (TDD) in our team. And I'm learning Ionic for myself. I endep up in this video to learn how to test with Angular. Didn't watch it all, only the intro, and I'm amazed so far. Thank you! Will watch the entire video later.
Excellent tutorial. Though the introduction is one of the best and is absolutely useful to watch ,14:50 is tutorial start point in case anyone wants to move fast.
This was a really good video that addresses a lot of real word questions and issues. I love the part about "you're not coding for fun, your job is to deliver". So spot-on, that perspective comes with experience. Thanks Mosh!
IMO testing a component and its template is an Unit Test. Why? Because the template is part of the component, irregardless of it being in a different file. The responsability of the component class is shared by the template. Both the view (template) and the model (class) have to exist and form a unit.
I have a question. Do we really need to write unit tests along with integrated tests? It seems that the way you defined integrated test it could cover all unit tests issues.
Good question and something many people wonder about. Unit tests and integration tests are testing for different things. It's like saying "do I need to have a door in a car... I could just get out of the boot". Anyone would say, well, you "could" get out of the boot, but it's quite cumbersome to do so and will take you much longer each time you need to get in and out of the car. Integration tests are more costly to maintain and run, so the majority of your testing can and should be in unit tests, and your integration tests cover just that, the interractions and integarations between components.
Hey Mosh, I was waiting for your answer to the question whether to Test first or to write Production Code first. Did I miss it? Would be curious what your thoughts are on that.
Let me to add something. When we commencing working on a project and the architecture of the project is unstable. We should avoid TDD for modules and components which may be removed later. Otherwise we might spend a lot of time on testing a garbage.
Hi Mosh, Great and simple understandable tutorial .From where i access 2nd part of this tutorial .I am unable to find it.I just want access to your unit testing course.
Great Course on unit testing which focuses more on client side. I have researched few tutorials , nothing helped me out. I have bought all your courses from your website ( codewithmosh.com). Unfortunately, this course is not included in " All courses section in your website "
Hey Mosh, great video. Is this full course only on udemy? You mentioned you're a pluralsight author as well. I have a pluralsight account, be great if this was on there as well.
In development process, developers follows MVC Framework structure so In Automation,is it possible to follow the same and if yes then in automation what should be take under M,V & C?
Nice tutorial. Regarding the test labelled "should increment the input if it is positive", this is a great description for a spec, but it does not precisely describe the test case. Imagine "should increment the input if it is positive" passes, but compute(3) returns 2. Imagine the minds inclined to believe that tests aren't useful; good luck convincing them otherwise after this happens.
Then your test is fucked up and doesn't match the description. If you pass 3 you expect 4. So if you give 3 and it returns 2, the test must failed. Or there is something I didn't understand ?

I think the vertical line is a reference to a formatting style. The style is keeping a space between the three lines of code within the it( // arrange line 1...........of code // act line 2...........of code //assert line 3...........of code ) test.
This is a philosophical discussion on the value of testing, I'm at minute 8 and so far, yes, I agree, testing needs to be pragmatic, but goodness, get on with it already.
does this course teaches how to setup my environment in order to start using unit test? I have been struggling for hours to start setup my it on my project without success
Mosh do you have any CSS beginner-advanced courses on Udemy.com? Because I can't find any... NOBODY teaches CSS correctly and right now you are my only hope... Please don't give me other sources, I'm only willing to buy courses directly from Udemy. Thank you :)
hello, i am enrolled in your testing angular 4 apps with jasmine and karma and i downloaded the zip file for unit testing fundamentals and i put in ng test and i get back "the test command requires to be run in an Angular project, but a project definition could not be found" and i can't find any solutions online. was hoping someone else came across this issue and would be able to help me :( thank you!
15:30 some people say you should write test code quite differently from production code. Watch ua-cam.com/video/oO-FMAdjY68/v-deo.html "Why Good Developers Write Bad Tests". For example you can repeat yourself. You should not factor too much.
Hi Mosh: I'm intrigued to know how you can get spec.ts files to appear in Chrome console, so you can put breakpoints on it. Per the Angular documentation here: angular.io/guide/testing#test-debugging Step 5 with CMD-P doesn't enable me to select file. Is there some sort of tweak you can do to karma.conf.js to allow this. All I see is something via polyfillls in Chrome 59 on a Mac with Sierra 10.12.5 when a test fails. That's not as intuitive as the original spec.ts source. I'm using Karma 1.7 and basically setup a project with ng new then merged it into the Tour of Heroes part 6 zip. Actually they have a zip file that enables the characterstics angular.io/generated/zips/testing/1st-specs.testing.zip It's a shame Angular guys didn't do a video talking through the config. There's a lot to it..
Could you update this course on Udemy? after I use Ng serve it tells me "The serve command requires to be run in an Angular project, but a project definition could not be found." (I have ran NPM install ofc)
hello, you can follow my channel I will be making angular 9 course with testing. The code will be available in my github repository. If you don't understand anything you can mention in the comment and I will try to help or cover in the next video.

The most beautiful explanation at all I loved Angular because of the way you explain Thank you Mosh 🌸💙
Mosh, you explained it in a very simplified way, I like it. its awesome. Keep it up , buddy.
Excellent tutorial.
Though the introduction is one of the best and is absolutely useful to watch ,14:50 is tutorial start point in case anyone wants to move fast.
great video! from the relaxing jazz to the clear and methodical explanations, this is a great intro. thanks!
Why didn't you include a link to the project's github/zip in the description?
Amazingly detailed. Thank you so much for being so precise.
All this while I have been searching to find course coupon ---- However Now, I am buying out this course rightaway!
This was a really good video that addresses a lot of real word questions and issues.
I love the part about "you're not coding for fun, your job is to deliver". So spot-on, that perspective comes with experience. Thanks Mosh!
Une très belle introduction aux tests front.
Je pense que je vais écrire mon premier test front lundi 😉
Merci beaucoup
Hi Mosh, I'm a big fan of your tutorials. You have said you have attached zip file with this video? Where can I find it?
Your explanation is very unique and interesting mosh. thank you for the wonderful videos :)
Wonderful tutorial. I got the detail understanding of testing within an hour. Thank you for this tutorial
It's an excellent tutorial. I am really glad to find it.
Your explanation is awesome maan, thank you for making these videos
Thank you mosh...it really helps a lot and able to understand quickly.
My job just asked me to do some ui testing. This video was super clutch
Made my day! Thanks for this! A sigh of relief!
You should have split this into two different Tutorials, general introduction about testing and the introduction in Jasmine and Karma!
Great intro to Jasmine and Karma. Thanks.
Wow, Amazing tutorial, It saves my life :D. Thank you @mosh
Thanks Mosh its very helpfull and crystal clear , it my first point to understand testing in angular and I am clear ;)
Thanks for the simplification
very clear explanations, thank you
Thank you so much Mosh for great explanation 👏
Great video, Nicely explained
Hi Mosh, I am taking your course in Udemy, however I could not find the zip file with the code to test, please help!
What a great tutorial Mosh !!! Thanks. regards.

Thanks Mosh for another great video!
Thanks mosh!
Where is the Zip file?
I couldn't find it either but I found the codes here way2programming.com/angular/unit-testing
Very solid tutorial... good job Mosh!
Thank you sir..this was helpful

that's incredible and amazing.

Excellent tutorial!
Great Tutorial.. Thanks Mosh!
Hello Mosh..very helpful tutorial. Where can i find the source code for this?
did you find that?
Cant find the zip download link
Hey Mosh,

great
I thought it was about writing maintainable code in time ;-)
Man, a very good tutorial !
very good tutorials
Amazing course mosh. How can we get a discount for your Udemy course ?
Hi Mosh, Great and simple understandable tutorial .From where i access 2nd part of this tutorial .I am unable to find it.I just want access to your unit testing course.
You're awesome. Thank you so much.
GREAT tutorial
Got it, thanks a lot!
Great Course on unit testing which focuses more on client side. I have researched few tutorials , nothing helped me out. I have bought all your courses from your website ( codewithmosh.com). Unfortunately, this course is not included in " All courses section in your website "
Where is the zipped file attached over here? I am a beginner to learning jasmine? Is ths tutorial the right one to start up ?
Hey Mosh, great video. Is this full course only on udemy? You mentioned you're a pluralsight author as well. I have a pluralsight account, be great if this was on there as well.
In development process, developers follows MVC Framework structure so In Automation,is it possible to follow the same and if yes then in automation what should be take under M,V & C?
Start at 8:39 if you are well aware of what testing is and why automation is needed
Thanks Mosh!
Thanks for your nice tutorial. Good luck
Thanks!
Great video!
please where can i download the file for this tutorial i can't find it
code here way2programming.com/angular/unit-testing
Hi Mosh, I was facing error while running individual component from my project can you please tell me how we can execute the component with example
Nice tutorial, but I find problems when you work with RXJS. Karma definitely doesn't go well with it.
Nice tutorial.

Awesome tutorial
Amazing video
Where can we find the zip angular project code?
At 15:25 you mention an attached zip file and direct us to download it. I see no attached zip file. What am I missing?
Where is the Zip file man?
Is a part of the payed course
Write your own code, that's a good way to learn and also help you remember the concepts covered here.
@@nickeax Think and after type, boy!
i am waiting for the second part! Great tutorial!
06:06 devEd on the left
27:52 "always put a vertical line between these lines" What is a vertical line?
I think the vertical line is a reference to a formatting style. The style is keeping a space between the three lines of code within the it(
// arrange
line 1...........of code
// act
line 2...........of code
//assert
line 3...........of code
) test.
awesome👍
Hi mosh. How to get the spec results on karma debug runner browser instead of console?
This is a philosophical discussion on the value of testing, I'm at minute 8 and so far, yes, I agree, testing needs to be pragmatic, but goodness, get on with it already.
very grateful for this content, you've convinced me =)

Amazing tutorial, my only regret is that I only have one thumb to give!
Technically you have two.. dislike is THUMBS down
Fantastic Bro !
Thanks for the one more great video
hello, i am enrolled in your testing angular 4 apps with jasmine and karma and i downloaded the zip file for unit testing fundamentals and i put in ng test and i get back "the test command requires to be run in an Angular project, but a project definition could not be found" and i can't find any solutions online. was hoping someone else came across this issue and would be able to help me :( thank you!
Awesome. Thanks
Great job.
Hi, Can you please help how to write unit test case for
Can you please share link of project to download. Thanx in advance
15:30 some people say you should write test code quite differently from production code. Watch ua-cam.com/video/oO-FMAdjY68/v-deo.html "Why Good Developers Write Bad Tests". For example you can repeat yourself. You should not factor too much.
Where is the Zip file that you are talking about in this video?
Hi Mosh!
Probably an odd question, but how do you auto import your functions at the top? Is there a keyboard shortcut for VSC to do this?
yes, even i am also eager to know..
There's another called Auto Import too
He uses Auto import because he said it in another video.
Type autoimport in vscode market place
I Have Been Learning AngularJs 1 And I Wanna Know When To Know Im' Good Enough To To start learning Another Javascript Framework Or Library ?
I am unable to find the download link to download the code to test, please help
You didn't added the zip file?
11:30 that few pixels off are giving me anxiety...
hello, guys how can we create only spec file in the component.
Hi Mosh: I'm intrigued to know how you can get spec.ts files to appear in Chrome console, so you can put breakpoints on it. Per the Angular documentation here: angular.io/guide/testing#test-debugging Step 5 with CMD-P doesn't enable me to select file. Is there some sort of tweak you can do to karma.conf.js to allow this. All I see is something via polyfillls in Chrome 59 on a Mac with Sierra 10.12.5 when a test fails. That's not as intuitive as the original spec.ts source. I'm using Karma 1.7 and basically setup a project with ng new then merged it into the Tour of Heroes part 6 zip. Actually they have a zip file that enables the characterstics angular.io/generated/zips/testing/1st-specs.testing.zip It's a shame Angular guys didn't do a video talking through the config. There's a lot to it..
With the current version, it inside main.bundle.js. So from step 4, CMD-P to search: main.bundle.js then set breakpoint
What about using PhantomJS instead of Chrome for testing?
Could you update this course on Udemy? after I use Ng serve it tells me "The serve command requires to be run in an Angular project, but a project definition could not be found." (I have ran NPM install ofc)
add angular.json file, you've copy project....
Hello, Could you provide me source of data files, because I just started learning testing...and I need to learn. Thanks for the same.
hello,
you can follow my channel I will be making angular 9 course with testing. The code will be available in my github repository. If you don't understand anything you can mention in the comment and I will try to help or cover in the next video.
