How to use benchmarks?

[ra0x3]

I followed the README in fuel-indexer-benchmarks and received the following error

running 0 tests

test result: ok. 0 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.00s

@deekerno How do I get this to work? I'm trying to confirm that 0.19.0 is slower than 0.18.5

The WASM benchmarks use the same database isolation setup as the end-to-end tests, so you may need to make sure that your DATABASE_URL environment variable will resolve correctly.

Works thanks!
