5# RSpec Test Instructions
6 
7## Conventions
8 
9- Follow [Better Specs](https://www.betterspecs.org/)
10- Mirror `lib/` structure: `lib/msf/core/exploit/remote/http_client.rb` → `spec/lib/msf/core/exploit/remote/http_client_spec.rb`
11- Use `described_class` instead of repeating the class name
12- One expectation per example when practical
13- Use `let` and `let!` for setup, `before` for side effects
14 
15## Running Tests
16 
17- Single file: `bundle exec rspec spec/path/to/spec.rb`
18- Single example: `bundle exec rspec spec/path/to/spec.rb:42`
19- Full suite: `bundle exec rake spec` (slow — avoid during development)
20 
21## Test Data
22 
23- Use TEST-NET-1 (`192.0.2.0/24`) for example IP addresses — never real IPs
24- Use `Rex::Text.rand_text_alphanumeric` for random test data
25- Use the `Faker` gem (e.g. `Faker::Internet.username`) for usernames/accounts
26 
27## Module Specs
28 
29- Module functional tests live in `spec/modules/`
30- Test end-to-end behaviour including `check` and `exploit`/`run` methods
31 
32## What to Test
33 
34- Public API methods — inputs, outputs, edge cases
35- Error handling paths — verify correct exception classes raised
36- Protocol parsing — round-trip encode/decode
37- Version comparison logic — boundary conditions
