HMRC recognition 

Exact, to the penny

We use 15 different imaginary taxpayers to exactly match all 4,300 of HMRC's model tax calculations.

Each of these tax calculations are matched to the penny, giving us recognition from HMRC that our tax software is 100% correct.

And, of course, we sit down and re-verify them all with HMRC every year.

Click tests 

Everything. Clicked.

Every night, we use robots to do 8,700 clicks through our product on 4,300 pathways. This pushes our test server's 8-core CPU to 100% for over 7 hours straight.

On each pathway, a tiny robot clicks a different path through our product as fast as the CPU will allow.

If the robot spots anything wrong, it takes some screenshots and notes, so we can put up a fix the very next day.

Unit tests 

Tried-and-tested

Every developer, twice a day, runs thousands of asserts to test our software. This includes 7,000 tax asserts, and 15,000 system asserts. That's 21,000 in total.

This makes sure that day-to-day software changes don't accidentally break our existing code.

Code checks 

Squeaky clean

Every developer, twice a day, runs 1,500 code checks. These code checks scan the 6,100 files in our codebase, looking for things to improve in the code.

This way, each day's changes are continuously scrubbed clean.
