The Need of Unit Testing in Software Development

Imagine the architect building your dream house skipping your ventilation or forgetting to leave points for power plugins. Wouldn’t it be odd? Of course it will be

app testing

Just like that, unit testing is also something you cannot afford to forget while building up a software.

So what is this unit testing?

3 Key Fears of Software Testing Professionals

Unit testing is a part of software testing like integration testing, penetration testing, usability testing and so on. In unit testing, a program or software is divided into the smallest functional unitsmaking testing effective and helps testers find out bugs easily. Unit testing is not something that produces an end product, but it is something that goes on with the process

In fact, unit testing makes your job easy.

In the developmental stage itself, unit testing reduces bugs which save time and money in the long run. As unit testing breaks software into simple codes and undergo testing of functionalities one by one, it gives more clarity and enables testers to find errors instantly.

You know what happens when you have a tendency to postpone unit testing ?

Testers have the tendency to drop unit testing for later, considering it as the last thing to do.

This happens not because developers are lazy, (unless they actually are’) ;But because unit testing is different from all other kinds of testing. Unit testing requires totally different kind of programs, written to test the function and logic errors of a software.

It has to be maintained throughout the life time process of a software.

Try cutting it down to the line and you face the risk of critical errors costing you.

How unit testing reduces bugs?

Don’t worry, this is not going to cost you any extra money.

Then how is it going to work? Let’s take a look

Effective unit testing happens with a good developer. Some suggest that keeping codes in written formats helps you understand codes better. Even though smaller projects may benefit from unit testing, larger projects are the usual ones that are in immediate need of unit testing. For them it’s mandatory.

If unit testing is going to be the very next step after creating initial prototype, then developers and clients have to be aware about the time needed to develop unit testing at the time of developing project.

Patience in doing unit testing brings difference. Take a little time and get the job done, don’t act quickly.

Since unit testing is done in modules, it’s easy to understand the additions and changes done to the software.They won’t get mixed with other codes or sections. Unit testing can provide a classic quality to your software.

Always remember to avoid complicated codes and pay some attention to threat warning.

‘Thinking twice’ and checking twice can also help in successful testing.

Objectives of unit testing

when writing unit testing don’t forget to remember these three points:-

  1. Codes should be readable

  2. Allow automation testing

  3. Written tests should be manageable.

How you can benefit from unit testing

  • Quickly allows to make changes
  • Saves time
  • Test driven development tell you when to stop coding
  • Helps define and document what something is supposed to do.
  • Codes can be re-used in new project
  • Coding constipation can be fixed by test-driven development, they help in fast movements of complicated codes
  • Test driven development brings a successful outcome combining the codes and test work together
  • Instead of constructing a code, testing outlines all the codes you need and brings out what developer wants the codes to do. 
  • Instant visual feedback
  • Unit testing helps developers understand the code instead of writing code for an expected outcome.

5 Conditions to be Added in Your Mobile App Testing Checklist

We can see developers setting new trends with exciting mobile applications every minute. But, this large number of apps leaves the consumers or the users in doubt, in terms of choice and their working.Therefore, app developers have mobile app testing or QA kept in top of their priority list so that their mobile applications are the best and defect free.
mobile app
We all know what mobile application bugs can do to mobile devices. An average mobile user will not prefer bugged applications in his/her device Therefore, in order to make it perfect, the mobile applications are tested.
Before you start testing, here are some key points to add to your checklist:

1. Performance

The performance of app focuses on mainly two things:
working speed of the app and the responsiveness of the application, the CPU of the device, memory usage in SD card and in device and the battery drainage.
Even a minor or major weakness in the network connection can affect the performance strength of the application. This is a kind of device versus application. So testing focused on the Wi-Fi connection or network availability can help to improve these areas of crashes.
This also covers the amount of data used by the application. This is one of users favourite too. Performance is merited on the basis of how well applications behave on the device.

2. Interruption

Bugs are well known to interrupt working of devices. While the app is running, normal interaction is interrupted by different kind of external events.
This includes pop up alert like alarms, calendar, notifications, incoming /outgoing voice calls and text messages. Among these the incoming/outgoing calls are the most important kind of interruption caused.
Sometimes, this can affect the working of other apps in the device too. This is almost common for every application. Clearing this defect before launching the app in the market can add to its efficiency.

3. Device Integration

Integration of the mobile application with the device is significant.
Here the applications have to merge with all the settings, configuration, alignment and in built applications of the mobile device such as screen resolution, screen orientation, OS, camera, audio, GPS service etc., It is very important to know how an app works on specifications like your location, video and camera.
Expected results may vary according to the specifications of the mobile.
Response of device to the gestures can also be included and how the device responds should also be counted.

4. Installation

Installation is the part where the tester should look for the process of installing and uninstalling and the properties of updating.
Sometimes, testing of installation in the application is not done completely.
There are a lot of things to consider while testing the installation of a mobile application. Initially, we have to categorize the end users. The target audience have a relationship with the process of installing and uninstalling the application.
app testing
Also, the experience can vary for the first time users of the application. The process of updating the installed application has to be taken care of. The main question that arises here is whether the updated version of a mobile application is supported by the device?

5. Network

Testing on network deals with the poor or weak signal, quality loss and data transition.
Applications that don’t need network traffic after the installation wouldn’t be much affected. The main course problem with the application that requires network data for further working is that, they have a tendency to consume a large amount of data. MB. Messenger applications are one among these.
Battery drain can also happen while in-app use. Gaming apps having multi-player specifications and applications like sound cloud where user can listen to music online can cause huge battery drainage.
