// TestMeta generates a random set of operations to run, then runs multiple
|
|
// instances of the test with varying options. See standardOptions() for the set
|
|
// of options that are always run, and randomOptions() for the randomly
|
|
// generated options. The number of operations to generate is determined by the
|
|
// `--ops` flag. If a failure occurs, the output is kept in `_meta/<test>`,
|
|
// though note that a subsequent invocation will overwrite that output. A test
|
|
// can be re-run by using the `--run-dir` flag. For example:
|
|
//
|
|
// go test -v -run TestMeta --run-dir _meta/standard-017
|
|
//
|
|
// This will reuse the existing operations present in _meta/ops, rather than
|
|
// generating a new set.
|
|
//
|
|
// The generated operations and options are generated deterministically from a
|
|
// pseudorandom number generator seed. If a failure occurs, the seed is
|
|
// printed, and the full suite of tests may be re-run using the `--seed` flag:
|
|
//
|
|
// go test -v -run TestMeta --seed 1594395154492165000
|
|
//
|
|
// This will generate a new `_meta/<test>` directory, with the same operations
|
|
// and options. This must be run on the same commit SHA as the original
|
|
// failure, otherwise changes to the metamorphic tests may cause the generated
|
|
// operations and options to differ.
|
|
//
|
|
// Each instance of the test is run in a different process, by executing the
|
|
// same binary (i.e. os.Args[0]) and passing `--run_dir`; the "inner" binary can
|
|
// be customized via the --inner-binary flag (used for code coverage
|
|
// instrumentation).
