示例1: test_unique_path_traversal
# 需要导入模块: from spack.spec import Spec [as 别名]
# 或者: from spack.spec.Spec import preorder_traversal [as 别名]
def test_unique_path_traversal(self):
dag = Spec('mpileaks ^zmpi')
dag.normalize()
names = ['mpileaks', 'callpath', 'dyninst', 'libdwarf', 'libelf',
'libelf', 'zmpi', 'fake', 'zmpi', 'fake']
pairs = zip([0,1,2,3,4,3,2,3,1,2], names)
traversal = dag.preorder_traversal(cover='paths')
self.assertListEqual([x.name for x in traversal], names)
traversal = dag.preorder_traversal(cover='paths', depth=True)
self.assertListEqual([(x, y.name) for x,y in traversal], pairs)示例2: test_normalize_with_virtual_spec
# 需要导入模块: from spack.spec import Spec [as 别名]
# 或者: from spack.spec.Spec import preorder_traversal [as 别名]
