Testing guide

Run unit and integration tests

You can run the unit and integration tests by:

cargo test --target x86_64-fortanix-unknown-sgx

Some features of cargo test are not yet supported in Fortanix EDP, notably

  1. Detect default number of threads - The default number of threads has been set to 1.
  2. Set RUST_TEST_THREADS - This environment variable is ignored.
  3. Pass command-line arguments (no-capture, test filtering, etc.) - These arguments are not propagated to the enclave.

Specify stack-size, heap-size and/or number of threads.

Depending on your application, you may want to increase the stack or heap size or the number of threads. You can do this by providing custom values under [package.metadata] table in Cargo.toml.
