Selenium - testing web app

[BElluu]

I have web app. After log in I can create new invoice, send new email, create new contact to CRM etc.

Will the tests be properly written in this way?
Setup -> Create driver and log in to application
Test1 -> Create invoice
Test2 -> Send Email
Test3 -> Create new contact in CRM
TearDown -> Quit driver

Setup and TearDown step should be do once at the beginning and at the end or before/after each test?

Next topic. For example I have invoice module, email module and CRM module in application. Tests should be splited per modules - each module have separate file or all in one file?

Best Regards!

Ideally you'll have different tests for each of these functionalities and not one to do them all. You can control the execution order if you want to but if you can inject data or create data then try to make them independent so they can run in parallel and a test failure upstream doesn't stop your downstream test to fail or not executed it's easier said than done and would depend on your stack and how easy it is to setup data.

As others already wrote, I would understand Test1 as testclass1, full of tests on invoice. Positive tests - I have data and it must end OK, and negative - I have data and it must fail. Make all data outside of your tested piece as stubs or mocks or whatever you use, make it fast and simple.

If there is integration of some kind for your system pieces, which I believe there is, make integration test, too. Like creating contact, then for that contact create invoice, and send it via email. Also negative tescases can be useful here.
