// We want to test many ops in deno which have different behavior depending on
|
|
// the permissions set. These tests can specify which permissions they expect,
|
|
// which appends a special string like "permW1N0" to the end of the test name.
|
|
// Here we run several copies of deno with different permissions, filtering the
|
|
// tests by the special string. permW0N0 means allow-write but not allow-net.
|
|
// See tools/unit_tests.py for more details.
