E2E Prisma helper

This is a tiny script that is used to run our E2E tests via Prisma and @open-policy-agent/ucast-prisma.

It's invoked by e2e/compile/e2e_test.go for a subset of the tests. It reads UCAST conditions (as JSON) on STDIN, converts them to Prisma filters, and then runs a "SELECT * FROM ..." query (findMany) against the fruits table like the other tests. The returned rows are printed as JSON on STDOUT.

Test a change

To use a local change to ucast-prisma with the Compile E2E suite, you'll have to do this:

In package.json, replace the line with "@open-policy-agent/ucast-prisma" with the following:

"@open-policy-agent/ucast-prisma": "file:../../../opa-typescript/packages/ucast-prisma"

Also run npm run build in "opa-typescript/packages/ucast-prisma" to make sure the changes are built. Run npm i in e2e/prisma, and then run the E2E tests for the prisma-enabled subset:

go test -tags e2e ./compile -run 'TestCompileHappyPathE2E/postgres/prisma/.' -v
