mini-grep's Issues

Make unit test for the class Command

Make unit test for the class Command to test:

Creation with build
Creation with try_from_iter
Execution of the command search

Add run guide

Add a run guide to execute mini-grep.

Document the code

The class Command must be documented to:

How create it
How use it

Add the possibility to ignore the case

Implement the possibility to ignore case of the pattern, with the environment variable 'IGNORE_CASE'.

Tests:

: Update test to use the case mode sensitive by default.

Note that unit tests are replaced by e2e tests.

Check that tests pass for unix and windows

Curently, Windows tests pass but we need to test that we get teh repository in a new install, all tests pass too.

In the same time, we need to check that tests pass for Unix platform.

Improve tests by removing unwrap

Check tests and remove overused unwrap.
