#load_data(file_name)

This method provides Data-Driven-Test functionality.

Load test data from the file. This is shorthand to load test data from file. If you want to load complex file, you can use #data with block.

Examples:

Load data from CSV file

load_data("/path/to/test-data.csv")
def test_empty?(data)
  assert_equal(data["expected"], data["target"].empty?)
end

Parameters:

file_name (String) —

full path to test data file. File format is automatically detected from filename extension.

Raises:

(ArgumentError) —

if file_name is not supported file format.
