Initializes library dir to store cassette json files.

• vcr_dir: directory for storing recorded json file.
• custom_dir: directory for placing custom json file.

This function can be used to filter headers from saved requests.

Examples

test "replace sensitive data in request header" do
  ExVCR.Config.filter_request_headers("X-My-Secret-Token")

  use_cassette "sensitive_data_in_request_header" do
    body = HTTPoison.get!("http://localhost:34000/server?", ["X-My-Secret-Token": "my-secret-token"]).body
    assert body == "test_response"
  end

  # The recorded cassette should contain replaced data.
  cassette = File.read!("sensitive_data_in_request_header.json")
  assert cassette =~ ""X-My-Secret-Token": "***""
  refute cassette =~  ""X-My-Secret-Token": "my-secret-token""

  # Now reset the filter
  ExVCR.Config.filter_request_headers(nil)
end

This function can be used to filter options.

Examples

test "replace sensitive data in request options" do
  ExVCR.Config.filter_request_options("basic_auth")
  use_cassette "sensitive_data_in_request_options" do
    body = HTTPoison.get!(@url, [], [hackney: [basic_auth: {"username", "password"}]]).body
    assert body == "test_response"
  end

  # The recorded cassette should contain replaced data.
  cassette = File.read!("sensitive_data_in_request_options.json")
  assert cassette =~ ""basic_auth": "***""
  refute cassette =~  ""basic_auth": {"username", "password"}"

  # Now reset the filter
  ExVCR.Config.filter_request_options(nil)
end

Replace the specified pattern with placeholder. It can be used to remove sensitive data from the cassette file.

Examples

test "replace sensitive data" do
  ExVCR.Config.filter_sensitive_data("<PASSWORD>.+</PASSWORD>", "PLACEHOLDER")

  use_cassette "sensitive_data" do
    assert HTTPotion.get("http://something.example.com", []).body =~ ~r/PLACEHOLDER/
  end

  # Now clear the previous filter
  ExVCR.Config.filter_sensitive_data(nil)
end

Set the flag whether to filter-out url params when recording to cassettes. (ex. if flag is true, "param=val" is removed from "http://example.com?param=val").

Skip recording cassettes for localhost requests when set

Skip recording cassettes for urls requests when set

Sets a list of headers to remove from the response

Throw error if there is no matching cassette for an HTTP request
