and exclude

Types
t :: [{atom, Regex.t | String.Chars.t} | atom]
Functions
Specs
eval(t, t, map, [ExUnit.Test.t]) ::
:ok |
{:error, atom}
Evaluates the include
and exclude
filters against the given tags
.
Some filters, like :line
, may require the whole test collection to
find the closest line, that’s why it must also be passed as argument.
Filters can either be a regular expression or any data structure
that implements to String.Chars
, which is invoked before comparing
the filter with the tag value.
Examples
iex> ExUnit.Filters.eval([foo: "bar"], [:foo], %{foo: "bar"}, [])
:ok
iex> ExUnit.Filters.eval([foo: "bar"], [:foo], %{foo: "baz"}, [])
{:error, "due to foo filter"}
Normalizes include and excludes to remove duplicates and keep precedence.
Examples
iex> ExUnit.Filters.normalize(nil, nil)
{[], []}
iex> ExUnit.Filters.normalize([:foo, :bar, :bar], [:foo, :baz])
{[:foo, :bar], [:baz]}
Parses the given filters, as one would receive from the command line.
Examples
iex> ExUnit.Filters.parse(["foo:bar", "baz", "line:9", "bool:true"])
[{:foo, "bar"}, :baz, {:line, "9"}, {:bool, "true"}]
