Widgets

Test tools

Added some static functions useful for unit tests for Flutter apps.

• runTestableWidgetScreen and runTestableComponent allow to launch a widget for testing with some parameters
• loadStringFromFile allows to load a string from a file in any test. Useful for loading JSON files for example.
• generateLongString generates a string of a given length and optionnaly we can decide which repeating character should be used. Useful for testing long texts in UI of widgets.

External contributions

If you want to add new widgets or extensions, please keep in mind before submitting a PR :

• Widgets and extensions must be generic enough to be usable in many projects
• Unit tests and automated tests are mandatory. 100% coverage is required for any newly added code

Thanks for your contributions!

Happy Coding.
