class RuboCop::Cop::RSpec::BeEq

Check for expectations where ‘be(…)` can replace `eq(…)`.

The ‘be` matcher compares by identity while the `eq` matcher compares using `==`. Booleans and nil can be compared by identity and therefore the `be` matcher is preferable as it is a more strict test.

@safety

This cop is unsafe because it changes how values are compared.

@example

# bad
expect(foo).to eq(true)
expect(foo).to eq(false)
expect(foo).to eq(nil)

# good
expect(foo).to be(true)
expect(foo).to be(false)
expect(foo).to be(nil)
