v0.4.0
Adds a new
param_feature
macro, which wraps Wallaby'sfeature
tests the same wayparam_test
wraps ExUnit'stest
.(While you can use the plain
param_test
macro in a test module that containsuse Wallaby.Feature
, doing so will break some Wallaby features including screenshot generation on failure.)Moves the
parse_examples/2
function, an implementation detail for theparam_test
macro, into a new private moduleParameterizedTest.Parser
.
v0.3.1
Bug fix to accept more unquoted strings, including those that have Elixir delimiters in them like quotes, parentheses, etc.
v0.3.0
New features
Support treating otherwise unparsable cells in your parameters table as strings
This is a quality of life improvement for avoiding needing to add noise to string cells:
param_test "supports unquoted strings",
"""
| value | unquoted string |
| 1, 2, 3 | The value is 1 |
""",
%{value: value, "unquoted string": unquoted} do
assert value == "1, 2, 3" and unquoted == "The value is 1"
end
Support a "description" column that will provide a custom name for each test.
If you supply a column named description
, test_description
, or test_desc
, we'll use that in the test name rather than simply dumping the values from the row in the test table. This lets you provide more human-friendly descriptions of why the test uses the values it does.
A trivial example (which also takes advantage of the support for unquoted strings):
param_test "failing test",
"""
| value | description |
| 1 | The value is 1 |
""",
%{value: value} do
assert value == 2
end
When you run this, the error will include the description ("The value is 1") in the test name:
1) test failing test - The value is 1 (MyAppTest)
test/my_app_test.exs:8
Assertion with == failed
code: assert value == 2
left: 1
right: 2
stacktrace:
test/my_app_test.exs:14: (test)
This is useful for communication with stakeholders, or for understanding what went wrong when a test fails.
v0.2.0
There are two new features in this release thanks to new contributor @axelson:
v0.1.0
Renamed to
ParameterizedTest
, with the accompanying macroparam_test
. (Why notparameterized_test
? It's longer, harder to spell, and there are a lot of other accepted spellings, including "parameterised," "parametrized," and "parametrised.")Added support for hand-rolled lists of parameters, like:
param_test "shipping policy matches the web site", [ # Items in the parameters list can be either maps... %{spending_by_category: %{pants: 29_99}, coupon: "FREE_SHIP"}, # ...or keyword lists [spending_by_category: %{shoes: 19_99, pants: 29_99}, coupon: nil] ], %{spending_by_category: spending_by_category, coupon: coupon} do ... end
Added experimental support for populating test parameters from CSV and TSV files. Eventually I'd like to extend this to other sources like Notion documents. (Feedback welcome—just open an issue!)
v0.0.1
Initial release.
