示例1: test_reparse_on_scope_change
# 需要导入模块: from openmdao.main.expreval import ExprEvaluator [as 别名]
# 或者: from openmdao.main.expreval.ExprEvaluator import _parse [as 别名]
def test_reparse_on_scope_change(self):
self.top.comp.x = 99.5

ex = ExprEvaluator('comp.x', self.top)
self.assertEqual(99.5, ex.evaluate())
self.assertEqual(self._ast_to_text(ex._parse()), "scope.get('comp.x')")
ex.scope = self.top.a
try:

except AttributeError as err:
self.assertEqual(str(err), "a: object has no attribute 'comp.x'")
else:

# 需要导入模块: from openmdao.main.expreval import ExprEvaluator [as 别名]
# 或者: from openmdao.main.expreval.ExprEvaluator import _parse [as 别名]
def _do_tests(self, tests, top):
