1 hour on writing the code, and then 30 minutes on testing. There were 3 tests in the class, the project isn't large, ~200 lines of code, and the point is that the team that deployed it failed to provide this.

It's not complicated; it's a failure in process and work that they are required to provide based on their Salesforce Partner agreements, and to meet minimum standards.

I already stated the language; it's written in Salesforce APEX. Yes, the code was reviewed and passed all tests within Salesforce as well.

Salesforce partners often upload "Dummy" test methods or fail to provide the test classes, as this requires additional time. It's more a reflection on the partner than the individual programmer, since I've been in the industry, I know that devs are thrown onto multiple projects at once.

However, with Agents, you can reduce that time. Nevertheless, companies are still failing to do even that. So that is why I think corporations are pushing for more agents; the basics are being skipped because the teams working on it don't have the time.
