It is better to check that as well: assert len(a) == len(set(a)) Yes, Yes, Yes: compare lists Using print statements for debugging ¶. One primary benefit of the default capturing of stdout/stderr output is that you can use print statements for debugging: # content of test_module.py def setup_function(function): print("setting up", function) def test_func1(): assert True def test_func2(): assert False. Using assert Statements. When you write test functions, the normal Python assert statement is your primary tool to communicate test failure. The simplicity of this within pytest is brilliant.

Using assert Statements. When you write test functions, the normal Python assert statement is your primary tool to communicate test failure. The simplicity of this within pytest is brilliant. It’s what drives a lot of developers to use pytest over other frameworks. Pytest assert string contains.

Note that all but the first line will be indented Assert that str matches regex in pytest Once in a while every Pythonista faces a need to test that some string value matches a regex pattern. When it comes we have no option but to use re module directly.

import re def test_something_very_useful(): value = get_some_string() assert re.match('\d+', value) Contains (String, String, String) Tests whether the specified string contains the specified substring and throws an exception if the substring does not occur within the test string. public static void Contains (string value, string substring, string message); static member Contains : string * string * string -> unit. Here is a basic pattern to achieve this: # content of test_sample.py def test_answer(cmdopt): if cmdopt == "type1": print("first") elif cmdopt == "type2": print("second") assert 0 # to see what was printed. For this to work we need to add a command line option and provide the cmdopt through a fixture function: Pytest assert string contains.

Hi @jrbenny35, thanks for reaching out!. I don't know the intricacies of the assertion rewriting myself, but you can start digging around the _pytest/assertion directory..

Fixtures. Tests frequently require some resources, which need to be available for the test. Learn what is pytest, how to install and use Python pytest with examples in this comprehensive pytest tutorial: A test is a code that checks the validity of the other code. Tests are designed to help in gaining confidence that what you wrote is working. It proves that the code is working as we want and get a safety net for future changes.

pytest_assertrepr_compare (config: Config, op: str, left: object, right: object) → Optional [List [str]] [source] Return explanation for comparisons in failing assert expressions. Return None for no custom explanation, otherwise return a list of strings. The strings will be joined by newlines but any newlines in a string will be escaped. Note In a python unit test (actually Django), what is the correct assert statement that will tell me if my test result contains a string of my choosing? self.assertContainsTheString(result, {"car" : ["toyota","honda"]}) I want to make sure that my result contains at least the json object (or string) that I specified as the second argument above One of the most common operations that programmers use on strings is to check whether a string contains some other string. If you are coming to Python from Java, for instance, you might have used the contains method to check if some substring exists in another string.

As the documentation says:. Using pytest.raises is likely to be better for cases where you are testing exceptions your own code is deliberately raising, whereas using @pytest.mark.xfail with a check function is probably better for something like documenting unfixed bugs Run tests by keyword expressions pytest -k "MyClass and not method" This will run tests which contain names that match the given string expression (case-insensitive), which can include Python operators that use filenames, class names and function names as variables. Fortunately recent PyInstaller releases already have a custom hook for pytest, but if you are using another tool to freeze executables such as cx_freeze or py2exe, you can use pytest.freeze_includes() to obtain the full list of internal pytest modules. How to configure the tools to find the internal modules varies from tool to tool, however. No matter whether it’s just a word, a letter or a phrase that you want to check in a string, with Python you can easily utilize the built-in methods and the membership test in operator.
