Writing Your Own Tests

The video tutorial guides viewers through writing and testing new functions in JavaScript. It focuses on creating test cases for temperature conversion functions, exporting them, and verifying their correctness using a test suite. The tutorial emphasizes the importance of testing to ensure code functionality and introduces basic testing concepts, preparing viewers for more advanced topics in future lessons.

What is the primary task described in the introduction of the video?

• Writing test cases for new functions

• Writing a new function

• Creating a new file

• Debugging existing code

What is the main goal of the temperature conversion functions?

• To convert Celsius to Rankine

• To calculate the average temperature

• To convert Fahrenheit to Celsius and vice versa

• To convert Celsius to Kelvin

What is the first step in writing the test cases?

• Importing the functions into the test suite

• Writing the test cases directly

• Creating a new function

• Running the test suite

Which function is tested in the first test case?

• Fahrenheit to Kelvin

• Celsius to Fahrenheit

• Fahrenheit to Celsius

• Celsius to Kelvin

What is the expected result when converting 32 degrees Fahrenheit to Celsius?

• 100 degrees Celsius

• 32 degrees Celsius

• 0 degrees Celsius

• 10 degrees Celsius

What is the expected result when converting 0 degrees Celsius to Fahrenheit?

• 0 degrees Fahrenheit

• 32 degrees Fahrenheit

• 10 degrees Fahrenheit

• 100 degrees Fahrenheit

What is the final step after writing both test cases?

• Ignoring the test results

• Writing additional functions

• Running the test suite to ensure all tests pass

• Deleting the test cases
