10 reasons why you should test your code

Code without a test is a ticking timebomb. Discover why it's important to test your code

Code without a test is a ticking timebomb. Discover why it’s important to test your code


1. Reduction of legal liability

In many jurisdictions, vendors are required to ensure their products are of marketable quality. Having a documented testing process can help you if sued due to software bugs. Worst comes to worst, you can prove that there wasn’t any malpractice, thereby reducing punitive damages or personal responsibility.

2. It’s good practice

Professionals enjoy working with other professionals. Any vendor which does not have a dedicated testing process reeks of unprofessionalism. Not having a test system complicates the hiring of experienced staff. Software developers can just quit their job due to lack of testing and documentation processes.

3. It increases motivation

Performing repetitive tasks demotivates people. Eastern European outsourcing vendors punish their customers for turning in unsorted piles of bills due to the detrimental effect on staff morale.
Automating your tests frees up developer and tester time for more important tasks.

4. It anticipates errors

The theory of falsification won a Nobel Prize. It states that a scientist should try to prove that his idea is wrong. It can be considered valid only if this process fails. Testing motivates developers to think about ways to break their code, thereby leading to more resilient applications.

5. It wins contracts

Some software-certification systems require the presence of a testing cycle. Not having one in place leads to your company failing inspections. When working for clients like the governmental or military, not having ISO certification is a deal-breaker and makes winning lucrative contracts difficult.

6. It reduces release anxiety

Some products suffer from slow release cycles: pushing out a product requires mental energy. Having a test cycle removes the QA step. This reduction in total effort tends to help anxiety situations as the total amount of effort is lowered by the reduction in the number of steps.

7. It simplifies fulfilling customer expectations

Ever had to turn down a feature request due to not being sure about how its integration will affect the rest of the product? If your code contains an ample amount of unit tests, adding a feature is as easy as coding it. Your computer will then take care of integration tests.

8. Tests are documentation

Ever suffered from not knowing how a newly acquired and quite complex system works? Well-written unit tests show how the individual classes work together to achieve one or more business tasks. Analysing that code permitts new developers figure out the internal workings of the system quickly.

9. Unit tests help you get zoned

Programmers and HR managers dream of the concept of the zone – a mental state where effectiveness reaches the highest possible level. Getting into it tends to require some introductory work, which is subject related but not particularly complex. Coding unit tests is an ideal example for such ‘menial tasks’.

10. It prevents catastrophic errors

If you release an application where a crucial feature doesn’t work it can result in huge monetal losses. A reliable set of tests mitigates this by ensuring that no products get shipped with significant defects.
