Bracket Push

Given a string containing brackets [], braces {} and parentheses (), verify that all the pairs are matched and nested correctly.

Running tests

Execute the tests with:

$ elixir bracket_push_test.exs

In the test suites, all but the first test have been skipped.

Once you get a test passing, you can unskip the next one by commenting out the relevant @tag :pending with a # symbol.

For example:

# @tag :pending
test "shouting" do
  assert Bob.hey("WATCH OUT!") == "Whoa, chill out!"
end

Or, you can enable all the tests by commenting out the ExUnit.configure line in the test suite.

# ExUnit.configure exclude: :pending, trace: true
