Fyi,
A new CAS integration test, called the "Elementary algebraic" integrals
version is now available.

This uses a subset of the full CAS integration tests and includes
a new 9th CAS integrate program IntegrateAlgebraic.
This subset includes only Algebraic integrals with optimal
antiderivatives made only of elementary functions.
These integrals are filtered out of the following Rubi's test files
provided thanks to Albert Rich
Algebraic Binomial
Algebraic Trinomial
Miscellaneous Algebraic
And also integrals from IntegrateAlgebraic test suite provided thanks
to Sam Blake.
This test was done to be able to include IntegrateAlgebraic in the
CAS integration tests, as IntegrateAlgebraic is meant to use only
on algebraic type of integrals.
There are 22,622 integrals in this Elementary algebraic integrals version.
The Full test suite on the other hand contains 71,994 integrals.
CAS Systems used in the Elementary algebraic integrals version test are
1. Mathematica 12.3.1 (64 bit) on windows 10.
2. Rubi 4.16.1 in Mathematica 12 on windows 10.
https://rulebasedintegration.org
3. Maple 2021.1 (64 bit) on windows 10.
4. Maxima 5.44 on Linux. (via sagemath 9.3)
5. Fricas 1.3.7 on Linux (via sagemath 9.3)
6. Sympy 1.8 under Python 3.8.8 using Anaconda distribution.
7. Giac/Xcas 1.7 on Linux. (via sagemath 9.3)
8. Mupad using Matlab 2021a with Symbolic Math Toolbox Version 8.7 under windows 10 (64 bit)
9. IntegrateAlgebraic under Mathematica 12.3.1 on windows 10.
