Data provider

Run multiple test cases for a given function (aka "data provider").

Arguments:

  1. func_name: The name of the function to be tested.
  2. args_per_row: (Optional) The number of arguments in each row of the TEST_CASES array, defaults to 1. Last argument is always the expected value.

Global Variables:

  • TEST_CASES: An array containing test cases with their expected values.

Examples:

To run a function add_numbers with TEST_CASES containing three arguments per row, you can call dataprovider_run like so:

# Function to test.
add_numbers() {
  echo "$(($1 + $2))"
}

@test "Test add_numbers" {
  # Numbers: first two are inputs, last is expected output.
  TEST_CASES=(
    1 2 3
    4 5 9
  )
  dataprovider_run "add_numbers" 3
}
