Pytest - Testing Framework

In this challenge you are supposed to write test cases based on given scenario

Instructions

• Read the instructions and code for the questions given
• file.pickle contains a list of words.
• Use assert function to check or assert
• Write the fixture function unpick which reads the pickle file "file.pickle" and return the list of words
• Mark the function as fixture
• Open the file "file.pickle" with "rb" and load the data using pickle.load function
• Write the test method test1 to check whether the count of words is equal to 6720
• Write the pytest test method test_len_endswith to check whether the count of words ending with 'ing' is greater than 350
• Write the pytest test method test_len_lessthan to check whether the count of words having characters less than 3 is equalto 80
• Write the test method test_keyword to check whether the count of keywords present in the list are not equal to zero
• Write the test method test_word to check whether the word "jupyter" is present in the list
• Write the test method test_len_startswith to check whether the count of words that starts with character 'c' is equal to 700
• Write the test method test_words_ag to check the count of words that starts with 'a' and endwith 'g' is a two digit number and the second digit is zero
• Write the test method char_words to check the whether count of words having alphabets only is greater than 6400
• Write the parameterized test method test_words_starts_with to run against a set of multiple inputs
• Mark the function as parameterize
• Write the function to check the count of words starting with the input character is equal to the output
• [('a',570),('e',327),('h',1296),('t',321)] is the set of inputs and outputs

IDE Instructions

Step 1:Coding

• Once the IDE is opened, Click File->New->Terminal and run the below command

  pip3 install -r requirements.txt
  

• Open test.py file and code for the questions given.

Step 2: Testing

• After Completing the solution, Save the test.py file .
• After saving the test.py file , Click File->New->Terminal and run the below command to generate test1.xml file

  pytest test.py --junitxml=test1.xml
  

• Now Click File->New->Terminal and run the below command to run test cases with keyword "len" and generate the test2.xml file

  pytest test.py -k len --junitxml=test2.xml
  

• Now test your solution by Click File->New->Terminal and run the below command to run sample test cases

  pytest sample_test.py
  

Step 3 : Submit the Solution

• Once all the sample test cases are passed, click 'Submit' to submit your solution to HackerRank.
