Skipping logic

[pgrange]

skip_if <condition> <pattern>

If condition is true, will skip all the tests in the current file which match the given pattern.

This can be useful when one has tests that are dependent on system environment, for instance:

skip_if "uname | grep Darwin" linux
skip_if "uname | grep Linux" darwin

test_linux_proc_exists() {
  assert "ls /proc/" "there should exist /proc on Linux"
}
test_darwin_proc_does_not_exist() {
  assert_fail "ls /proc/" "there should not exist /proc on Darwin"
}

will output, on a Linux system:

	Running test_darwin_proc_does_not_exist ... SKIPPED
	Running test_linux_proc_exists ... SUCCESS
