What is Picka?
Picka generates randomized data for testing.
Data is generated both from a database of known good data (which is included), or by generating realistic data (valid), using string formatting (behind the scenes).
Picka has a function for any field you would need filled in. With selenium, something like would populate the "field-name-here" box for you, 100 times with random names.
for x in xrange(101):
self.selenium.type('field-name-here', picka.male_name())
But this is just the beginning. Other ways to implement this, include using dicts:
user_information = {
"first_name": picka.male_name(),
"last_name": picka.last_name(),
"email_address": picka.email(10, extension='example.org'),
"password": picka.password_numerical(6),
}
This would provide:
{
"first_name": "Jack",
"last_name": "Logan",
"email_address": "[email protected]",
"password": "485444"
}
Don't forget, since all of the data is considered "clean" or valid - you can also use it to fill selects and other form fields with pre-defined values. For example, if you were to generate a state; picka.state() the result would be "Alabama". You can use this result to directly select a state in an address drop-down box.
Examples:
Selenium
def search_for_garbage():
selenium.open('http://yahoo.com')
selenium.type('id=search_box', picka.random_string(10))
selenium.submit()
def test_search_for_garbage_results():
search_for_garbage()
selenium.wait_for_page_to_load('30000')
assert selenium.get_xpath_count('id=results') == 0
Webdriver
driver = webdriver.Firefox()
driver.get("http://somesite.com")
x = {
"name": [
"#name",
picka.name()
]
}
driver.find_element_by_css_selector(
x["name"][0]).send_keys(x["name"][1]
)
Funcargs / pytest
def pytest_generate_tests(metafunc):
if "test_string" in metafunc.funcargnames:
for i in range(10):
metafunc.addcall(funcargs=dict(numiter=picka.random_string(20)))
def test_func(test_string):
assert test_string.isalpha()
assert len(test_string) == 20
MySQL / SQLite
first, last, age = picka.first_name(), picka.last_name(), picka.age() cursor.execute( "insert into user_data (first_name, last_name, age) VALUES (?, ?, ?)", (first, last, age) )
HTTP
def post(host, data):
http = httplib.HTTP(host)
return http.send(data)
def test_post_result():
post("www.spam.egg/bacon.htm", picka.random_string(10))
