[mattness]

Q	A
OS	macOS and Linux
Shell & version	bash 5.3.3 (macOS) and bash 5.2.32 (Linux)
bashunit version	0.24.0 (both)

Summary

data_set does not preserve trailing whitespace present in the final argument passed to it.

How to reproduce

This test currently fails:

# @data_provider provide_value_with_trailing_whitespace
function test_trailing_whitespace_in_last_value_from_data_provider() {
  local expected="$1"
  local actual="$2"

  assert_same "${expected}" "${actual}"
}

function provide_value_with_trailing_whitespace() {
  # Each data_set is passed the same value twice (expected, actual) to verify preservation
  data_set "value " "value "
  data_set "value    " "value    "
}

Output:

bashunit - 0.24.0 | Tests: 2
