How to write multiple test functions in a single file (TDD implementation)

I have different test cases to test the different functions. I want to write all the different functions in one .m file and one test file to check all the different test cases.

https://www.mathworks.com/help/matlab/matlab_prog/write-simple-test-case-with-functions.html#zmw57dd0e66668

I followed the above link but I can see only one test function implemented but I want to implement multiple functions. can anyone help me in implementing multiple functions ?

Each subfunction that starts or end with "test" is a seperate test procedure in the test file.

For example:

function tests = myManyTests()
tests = functiontests(localfunctions);
end

function test_function1()
% ...
end

function test_function2()
% ...
end

function test_function3()
% ...
end
