ptest 1.0.3

light test runner for Python

ptest is a light testing framework for Python. Using decorator to tag test classes and test cases, executing test cases by command line, and generating clear report.

Find the latest version on github: https://github.com/KarlGong/ptest or PyPI: https://pypi.python.org/pypi/ptest

Installation

The last stable release is available on PyPI and can be installed with pip.

$ pip install ptest

Best Practice

Firstly, create a python file: c:\folder\mytest.py

You can tag test class, test, before method, after method by adding decorator @TestClass, @Test, @BeforeMethod, @AfterMethod.

from ptest.decorator import TestClass, Test, BeforeMethod, AfterMethod
from ptest.assertion import assert_equals, assert_true, fail, assert_none
from ptest.plogger import info
from ptest import config

@TestClass(run_mode="singleline") # the test cases in this class will be only executed by one thread
class PTestClass:
    def __init__(self):
        self.expected = 1

    @BeforeMethod(description="Prepare test data.")
    def before(self):
        info("setting expected result.")
        self.expected = 10

    @Test(tags=["regression", "smoke"])
    def test1(self):
        assert_equals(10, self.expected) # pass

    @Test(tags="smoke, nightly")
    def test2(self):
        assert_none(config.get_property("key")) # assert the property defined via -D<key>=<value> in cmd line
        assert_true(False) # failed

    @Test(enabled=False)
    def test3(self):
        fail("failed") # won't be run

    @AfterMethod(always_run=True, description="Clean up")
    def after(self):
        info("cleaning up")

Then start to execute all the testcases in module mytest.py. Use -w to specify the workspace and -t to specify the target. In this case, workspace is c:\folder and target is mytest.

$ ptest -w c:\folder -t mytest

The target can be package/module/class/method. If the target is package/module/class, all the test cases under target will be executed. For example, if you want to execute all the testcases under class MyClass, the class is in module mypackage.mymodule.

$ ptest -t mypackage.mymodule.MyClass

If you have multiple targets, just separate them by comma.

$ ptest -t mypackagea.mymodule,mypackageb

For more options, please use -h.

$ ptest -h

Selenium Support

ptest supports capturing screenshots for failed selenium test cases. But you need to make a little change to your code.

Create a python file: c:\folder\seleniumtest.py

from ptest.decorator import TestClass, Test, BeforeMethod, AfterMethod
from ptest.assertion import fail
from selenium.webdriver import Chrome
from ptest import testexecutor

@TestClass(run_mode="parallel") # the test cases in this class will be executed by multiple threads
class SeleniumTestClass:
    @BeforeMethod()
    def before(self):
        self.webdriver = Chrome()
        # add browser to current testexecutor
        testexecutor.update_properties(browser=self.webdriver)

    @Test()
    def test1(self):
        self.webdriver.get("https://github.com/KarlGong/ptest")
        fail()

    @Test()
    def test2(self):
        self.webdriver.get("https://pypi.python.org/pypi/ptest")
        fail()

    @AfterMethod(always_run=True)
    def after(self):
        self.webdriver.quit()
        # remove browser from current testexecutor
        testexecutor.update_properties(browser=None)

Added following line after the browser is initialized.

testexecutor.update_properties(browser=self.webdriver)

Added following line after the browser is closed.

testexecutor.update_properties(browser=None)

Execute the test cases under module seleniumtest.py by 2 threads. Use -n to specify the number of test executors(threads).

$ ptest -w c:\folder -t seleniumtest -n 2
