TestSubprocessFlags

class TestSubprocessFlags

Flags to pass to test_trap_subprocess() to control input and output.

Note that in contrast with test_trap_fork(), the default is to not show stdout and stderr.

Fields

class TestSubprocessFlags

DEFAULT

Default behaviour. Since: 2.74

INHERIT_STDERR

If this flag is given, the child process will inherit the parent’s stderr. Otherwise, the child’s stderr will not be visible, but it will be captured to allow later tests with test_trap_assert_stderr().

INHERIT_STDIN

If this flag is given, the child process will inherit the parent’s stdin. Otherwise, the child’s stdin is redirected to /dev/null.

INHERIT_STDOUT

If this flag is given, the child process will inherit the parent’s stdout. Otherwise, the child’s stdout will not be visible, but it will be captured to allow later tests with test_trap_assert_stdout().
