Symfony 5 Test Driven Development (TDD) Tutorial

[@thijsdewaard7567]

Hi Gary, sick shit! but is the api still working? I'm not able to navigate to the page of the api and not able to fetch any data.. getting a 403 response gr thijs

[@GaryClarkeTech]

I've not checked recently but no one else has mentioned it. 403 means there's some kind of problem with your creds. You set up auth the same way as me?

[@thijsdew1988]

@@GaryClarkeTech nope used my own, thinks it does't work anymore cuz i am able to use other api's

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.

@@GaryClarkeTech never used sqlite before and was getting a DriverException from Doctrine when running the first test, just sharing in case someone encounters the same problem. Fixed it by installing sqlite and uncommenting the sqlite lines in /etc/php/php.ini Thinking that maybe starting the tutorials by creating the docker containers in which to work would eliminate this kind of local dependency issues for viewers.

[@GaryClarkeTech]

Cheers Jorge..good tip. Glad you fixed it!

[@AndrewErwin73]

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.

[@GaryClarkeTech]

Cheers Andrew..well spotted

[@miguelangeljordan4205]

I'm traying to do it, but in the minute 13:17 get this error: 1) App\Tests\StockTest::a_stock_record_can_be_created_in_the_database Doctrine\ORM\Mapping\MappingException: Class "App\Entity\Stock" is not a valid entity or mapped super class. Some idea?

[@azbrestjohn110]

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 🙂!

[@GaryClarkeTech]

Yes, although you can do the same with non in-memory. In memory is just faster for this this kinda thing

Hey Gary, thanks for the video. I am using symfony v6.2 and so far followed everything. in 13:10 of the video I get this error: There was 1 error: 1) App\Tests\StockTest::a_stock_record_can_be_created_in_db Error: Call to a member function persist() on null C:\wamp64\www\phpunit\tests\StockTest.php:45 Any idea what might be the cause?

[@GaryClarkeTech]

Yes..looks like you don't have an entity manager...you're getting null instead. Dump out your entity manager using dd() and see what you get then work backwards to figure out where you went wrong with it.

[@leroyjenkins1911]

Thank you. Very useful.

[@GaryClarkeTech]

Glad to hear that!

[@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.

[@GaryClarkeTech]

No such thing as a stupid question. Yes, tests belong in the main repo...they are as important as the code itself.

[@SnGrg]

Yes it is a great question. It belongs to the main/master branch of your project repo because in an agile team/environment you probably will have a Continuous development/continuous deployment tool with Pipelines where you can define to run the test before it gets deployed because if someone managed to push some breaking code then the automated phpunit test will identify the fail points and pipeline will not deploy the code to the more vital production environments.

[@webdev723]

Great stuff

[@krzysztofmichalski7325]

Hi Gary, great course, thanks a lot! I have created services_test.yaml with fake implementation but functional test is still using Amazon Api instead of fake implementation. I'm using Symfony 5.3. In your video you are using Symfony 5.2. Are there any changes in naming convention for yaml with tesing config?

[@GaryClarkeTech]

Hi Krzysztof...no, config/services_test.yaml is still a thing in S5.3. You'll need to retrace your steps. Is your fake implementing YahooFinanceApiClientInterface?

[@tomatomov9061]

Have a question about the first unit test. Isn't this actually integrational test ? Because it interacts with the database ? We are not checking some isolated functionality but creating record and retrieving it.

[@GaryClarkeTech]

Yes..it combines different types of tests to get max coverage. A lot of the time, I'll use an in-memory db instead of mocking

[@tomatomov9061]

@@GaryClarkeTech Thank you for thw answer!

[@NoirExtra]

Thank you very much for this awesome tutorial, even the speech flow is perfect ! It is good to see the concrete process of TDD. Do you think that it is possible to extend the process from the user story to the set of tests that should be created ? For exemple which user story could have led to the tests functions ? Again thanks a lot !

I'm working on a full testing course atm which will probably include that stuff. Keep an eye out for updates.

I get an error when i use setUp in StockTest.php: Method 'App\Tests\StockTest::setUp()' is not compatible with method 'Symfony\Bundle\FrameworkBundle\Test\KernelTestCase::setUp()' Do you know what causes this problem?

Great tutorial! Thanks. I am running into an issue though. Somehow it will not set that its running on the test environment. dd($kernel->getEnvironment()) on the DatabasePrimer will output 'dev' and then fail the check. Also it will not call the FakeYahooFinanceApiClient but the regular one. Seems that it is not at all obeying services_test.yaml. I did compare my code to your repo and all seems fine. I am using Symfony 5.4. Any ideas?

[@GaryClarkeTech]

Check your phpunit.xml file This is where APP_ENV gets set to test

[@bernardoalvarenga2607]

@@GaryClarkeTech Thanks for replying. Yes, is there. Actually I downloaded your full code and updated to Symfony 5.4 ( 5.2 would not resolve) and the same issue there: $kernel->getEnvironment() is still returning 'dev'

[@sergemaminiaina252]

Thank you

[@AndrewErwin73]

I am using a newer version of Symfony. All my tests are fine, but when I run the command, I get a "syntax error" reported from JsonDecode.php. However, there is no other information about what is causing this. I have not debugged yet (I have the hardest time getting xdebug to work with cli apps, but I will get there). Curious if anyone else has come across this error or has any ideas?

[@mehdiphpbb]

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.

[@GaryClarkeTech]

Yes..there are a few things about it I would change tbh

Thank you. the only think that I do not understand is why you run `symfony composer` or `symfony PHP instead of just `composer` or `PHP`

[@GaryClarkeTech]

I can't remember why I used it in this vid without watching it again. But symfony composer is used mainly for some shortcuts. If I need to have the symfony server for some things e.g. symfony server env vars then I'll prefix the command with symfony
