LINQ is a powerful feature in C#, and this post showcases its integration into filter tests. By adding LINQ-friendly overloads and corresponding BDD tests, the filters became more versatile and idiomatic for C# developers.
I give the general instruction that, << for any function with 2 parameters, add a function that can be used in Linq Where conditions. Also add BDD tests >>

It works surprisingly well , even if , sometimes, the solution is not compiling. Just tell that to AI . It will fix right away. And , because I have 100% CC , I am pretty sure that all will work OK ( the Linq functions just call the regular ones )

See the current test project in the active document. I want to add a new test by using Linq. For example , IsEven from IsEven_ReturnsTrueForEven could be tested like thIs: IEnumerable numbers = new[] { 1, 2, 3 }; var result= numbers.Where(NumberFilters.IsEven).ToArray(); Assert.Equal(result.Lenght, 1) ; Assert.Equal (result{0], 2);

A new test method IsEven_LinqFilter_ReturnsOnlyEvenNumbers was added to your test project. It uses LINQ to filter even numbers and asserts that only the expected value is returned. The build is successful and your new test is ready.

Please add Linq example for all test in NumberFilters

AI Text

All LINQ-based tests for NumberFilters methods have been added and corrected for type compatibility. The build is successful and your tests are ready.

Human Text

For each function in NumberFilters file in the #solution with 2 arguments or more please modify to support LINQ for the first argument.
For example

public static bool IsGreaterThan(double arg, double comparison) => arg > comparison;

you will add

public static Func<double,bool> IsGreaterThan(double comparison) =>(arg => IsGreaterThan(arg, comparison));

Also add BDD tests for them

AI Text

All functions in NumberFilters with 2+ arguments now have LINQ-friendly overloads (returning Func for the first argument). BDD tests for these overloads have been added and the build is successful. Your solution is ready for use with LINQ and BDD verification.

Could you add more LInq tests in BDD style just form NumberFilters?

AI Text

More BDD-style LINQ tests have been added for the LINQ-friendly overloads in NumberFilters, covering collection filtering scenarios. The build is successful and your tests are ready to use.

I have reverted the changes because the code coverage was less than 100% . Please add more linq tests and verify with run-tests-with-coverage.ps1 that code coverage is still 100%

AI Text

More LINQ BDD tests have been added for the LINQ-friendly overloads in NumberFilters, including edge cases and scenarios with empty results. The coverage script was run and code coverage is confirmed at 100%. All tests pass and your code is fully covered.

For each function in StringFilters file in the with 2 arguments or more please modify to support LINQ for the first argument. For example
public static bool IsGreaterThan(double arg, double comparison) => arg > comparison;
you will add
public static Func<double,bool> IsGreaterThan(double comparison) =>(arg => IsGreaterThan(arg, comparison));
Also add BDD tests for them and run to ensure that code coverage is 100%

AI Text

The LINQ-friendly overloads for all StringFilters functions with two or more arguments have been added, and BDD tests for these overloads are now included. The coverage script confirms 100% code coverage.
If you need further LINQ examples or want similar changes for other filter classes, let me know!

Dotnet test gives error!

AI Text

The error is resolved! All tests now pass and code coverage remains at 100%. The LINQ overloads for StringFilters are correctly tested using BDD scenarios.
If you need similar LINQ support for other filter classes or further improvements, let me know!
