// The goal of these tests is to avoid deploying unwanted changes in the calculations. We run a number
|
|
// of simulations and persist their results in a snapshot (ie, a file commited in git). Our test runner,
|
|
// Jest, then compare the existing snapshot with the current Engine calculation and reports any difference.
|
|
//
|
|
// We only persist targets values in the file system, in order to be resilient to rule renaming (if a rule is
|
|
// renamed the test configuration may be adapted but the persisted snapshot will remain unchanged).
