What clients say

“There’s a very narrow window for testing quarterly patches, so it’s an intense process. Assurity’s work streamlines this crucial task; without the support of automated testing, it’s hard to see how managing these updates would be feasible.”

Lara Ariell

CFO, Inland Revenue

“Automated testing and reusable test assets go beyond the value delivered to IR. It means each agency can access proven artifacts along with the reference architecture for systems implementation. And that means taxpayers get more value for their money as government agencies transform for the future.”
