`--pattern` option

When you run RSpec without giving it specific file names, it determines which
files to load by applying a pattern to the provided directory arguments or
spec (if no directories are provided). By default, RSpec uses the following
pattern:

"**{,/*/**}/*_spec.rb"

Use the --pattern option to declare a different pattern.

Background

Given

a file named "spec/example_spec.rb" with:

RSpec.describe "two specs" do
  it "passes" do
  end

  it "passes too" do
  end
end

And

a file named "spec/example_test.rb" with:

RSpec.describe "one spec" do
  it "passes" do
  end
end

Scenarios

By default, RSpec runs matching spec files
The `--pattern` flag makes RSpec run files matching the specified pattern and ignore the default pattern
The `--pattern` flag can be used to pass in multiple patterns, separated by commas
The `--pattern` flag accepts shell style glob unions

By default, RSpec runs matching spec files

When: I run rspec
Then: the output should contain "2 examples, 0 failures"

The `--pattern` flag makes RSpec run files matching the specified pattern and ignore the default pattern

When: I run rspec -P "**/*_test.rb"
Then: the output should contain "1 example, 0 failures"

The `--pattern` flag can be used to pass in multiple patterns, separated by commas

When: I run rspec -P "**/*_test.rb,**/*_spec.rb"
Then: the output should contain "3 examples, 0 failures"

The `--pattern` flag accepts shell style glob unions

When: I run rspec -P "**/*_{test,spec}.rb"
Then: the output should contain "3 examples, 0 failures"
