Symfony 5 Test Driven Development (TDD) Tutorial

ℹ In this 80 minute recording, I will build out a Symfony service, using Test Driven Development, which is able to make an HTTP request to an API and then store some of the returned data in a database.

Great content, mate!

As for a fresh graduate programmer this course helped me A LOT while solving the technical task required for job application. Thank you, learned so many new things while double watching this course <3

[velvetrev]

[FMB]

Amazing demo and great TDD mentoring!
This is great content 👏👏👏
I'd love to see more 🤞
Thanks for your work :)

[makomweb]

Thank you so much for this high quality content.
I learned so much from this video and appreciate how you explained all the details.
After I failed with Symfony 5.2 - I had a dependency version conflict with DAMA/doctrine ... - I was able to recode everything with Symfony 5.3 nicely.

WOW !! this is amazing !! Thank You Gary !!

[KwabenaAfreh]

This is very helpful. Simple and a good test strategy

[damne]

Awesome content Gary!! Will follow it and enjoy it this weekend!

[azbrestjohn]

Wow ! I didn't think that in-memory DB can be used for unit tests, thank you !
It indeed makes sense, because these DB are temporary, and each test have its own DB... This will avoid me to use mock objects to use the EntityManager then 🙂!

I've been using Symfony and Spring framework and if you learn one you learn the other one without much effort. Both are great frameworks.

In the price tests, you should test for assertIsNumeric because sometimes it sends back whole dollar amounts with no cents (and it does't display xx.00) when that happens, the test will fail.

[CaimAstraea]

Hmm I have a stupid question maybe :) Should tests belong in the main repo ? On the dev branch ? Or just keep them locally on my machine ? Because eventually what's on the dev branch will eventually be merged in the production and deployed.

Excellent tutorial, but you have extracted the finance API to an interface which completely dependent on Yahoo API, the fetch method should not have any arguments bonded to a specific API, maybe the next API does not require the symbol and region.

I'm traying to do it, but in the minute 13:17 get this error:
1)
Class "App\Entity\Stock" is not a valid entity or mapped super class.

Some idea?
