Every test that rails generate active_agent:agent writes fails while loading:

test/agents/support_agent_test.rb:3:in `<main>': uninitialized constant ActiveAgent::TestCase (NameError)

The TestUnit template inherits from ActiveAgent::TestCase, which the framework has never defined (the only other mention is a commented-out line in the Railtie). It fails even for an agent generated without actions, whose test body is all comments. The existing generator tests only matched the file's text, so they asserted the broken superclass instead of catching it.

What changes

• lib/generators/test_unit/templates/functional_test.rb.tt: generated tests inherit from ActiveSupport::TestCase, the class the docs' own test examples already use.
• test/generators/test_unit/agent_generator_test.rb: the text assertions expect the new superclass.
• test/generators/active_agent/generated_agent_test.rb (new): generates an agent into a scratch Rails host (framework railties plus active_agent, no Active Record) and runs the generated test file in a subprocess. Covers a plain agent, a namespaced agent and an agent without actions, and asserts the exact run and assertion counts.

Checks

• With the old template restored, all three new tests fail with the NameError above. With the fix, they pass.
• bin/test: 4095 runs, 0 failures, 0 errors. bin/rubocop reports no offenses on the changed files.

Thanks @yorzi — read through this one and it looks good to me. Tight scope, the root cause is right (ActiveAgent::TestCase has never existed), and I like that generated_agent_test.rb actually runs the generated file in a subprocess instead of just matching text. CI is green across all the gemfiles.

Before I merge: do you want a proper line-by-line review on this, or are you happy for it to go in as-is? And is there anything else you have planned on this branch, or is it done?

@TonsOfFun Thanks! I’m comfortable with this being merged as-is if you’re satisfied with the current review.

This branch is complete for the generated-test fix; I don’t have further changes planned for it.
