Write a formatted and readable unit test for any input

Contributed by: Jason Biggs

ResourceFunction["WriteUnitTest"][file,expr]

evaluates expr and uses the result to write a VerificationTest in file.

Details and Options

If file does not exist, it will be created. If it does exist, the new test will be added before the EndTestSection[] line.
If the option "ConfirmResults" is set to the default value of True, a dialog will appear showing the test before writing it to the file.

Examples

Basic Examples (2) 

Create a unit test and write it to file:

In[1]:=
ResourceFunction["WriteUnitTest"]["testFile1.wlt", f[x0_] :=
  Module[{x = x0},
   While[x > 0, x = Log[x]];
   x
   ];
 f[2.0]
 ]
Out[1]=

Run the test:

In[2]:=
TestReport["testFile1.wlt"]
Out[2]=

Options (2) 

Use the option "ConfirmResults" to write the test to file without verifying the results:

In[3]:=
ResourceFunction["WriteUnitTest"]["testFile1.wlt", 2 + 2, "ConfirmResults" -> False];
In[4]:=
ResourceFunction["WriteUnitTest"]["testFile1.wlt", 3 + 3, "ConfirmResults" -> False];
In[5]:=
ResourceFunction["WriteUnitTest"]["testFile1.wlt", 1/0, "ConfirmResults" -> False];

Each test was appended to the file:

In[6]:=
TestReport["testFile1.wlt"]
Out[6]=
