pnpm bazel run modules/benchmarks/src/tree/{name}:devserver

# e.g. "ng2" tree benchmark:
pnpm bazel run modules/benchmarks/src/tree/ng2:devserver

# Run e2e tests of individual applications:
pnpm bazel test modules/benchmarks/src/tree/ng2/...

# Run all e2e tests:
pnpm bazel test modules/benchmarks/...

The *_aot.ts files are used as entry-points within Google to run the benchmark tests. These are still built as part of the corresponding ng_module rule.

There are options that can be specified in order to control how a given benchmark target runs. The following options can be set through test environment variables:

• PERF_SAMPLE_SIZE: Benchpress performs measurements until scriptTime predictively no longer decreases. It does this by using a simple linear regression with the amount of samples specified. Defaults to 20 samples.
• PERF_FORCE_GC: If set to true, @angular/benchpress will run run the garbage collector before and after performing measurements. Benchpress will measure and report the garbage collection time.
• PERF_DRYRUN: If set to true, no results are printed and stored in a json file. Also benchpress only performs a single measurement (unlike with the simple linear regression).

Here is an example command that sets the PERF_DRYRUN option:

pnpm bazel test modules/benchmarks/src/tree/baseline:perf --test_env=PERF_DRYRUN=true
