15 application test engineer skills for your resume and career

1. C++

C++ is a general-purpose programming language that is used to create high-performing applications. It was invented as an extension to the C language. C++ lets the programmer have a high level of domination over memory and system resources. C++ is an object-oriented language that helps you implement real-time issues based on different data functions

Here's how application test engineers use c++:

Perform some Visual Basic, .NET, and C++ application software engineering (e.g.
Develop mathematical simulations of casino games using C++ in order to perform mathematical analysis to determine jurisdictional compliance of software.

2. Python

Python is a widely-known programming language. It is an object-oriented and all-purpose, coding language that can be used for software development as well as web development.

Here's how application test engineers use python:

Defined and implemented new validation tools and methods for test development and automation using Python and C#.
Developed Python scripts to search for test data in terabytes of archived text files.

3. Java

Java is a widely-known programming language that was invented in 1995 and is owned by Oracle. It is a server-side language that was created to let app developers "write once, run anywhere". It is easy and simple to learn and use and is powerful, fast, and secure. This object-oriented programming language lets the code be reused that automatically lowers the development cost. Java is specially used for android apps, web and application servers, games, database connections, etc. This programming language is closely related to C++ making it easier for the users to switch between the two.

Here's how application test engineers use java:

Conducted Functionality and GUI (Java Web Interface) testing manually and recorded scripts for WinRunner.
Designed, developed and implemented Keyword Driven automation testing framework utilizing Java, TestNG and Selenium Web Driver.

4. Test Cases

Here's how application test engineers use test cases:

Prepared automation test cases for application installation and analyzed application behavior using Batch and PowerShell scripts to automate repetitive tasks.
Developed test cases based on functional specifications and business requirements.

5. RF

Here's how application test engineers use rf:

Assisted in Design/Development of supervisory power control circuitry for portable RF Bar Code Scanner Systems - Versions 9462 and 9465RF.
Introduced new Hardware & Software test solutions for integrated RF Amplifiers, LNA's.

6. Debugging

Here's how application test engineers use debugging:

Set up Kernel-mode debugging to Virtual Machine Host and analyzed crash dump files using WinDbg.

8. Technical Support

Technical support or tech support are the services provided by any hardware or software company to users. They help in solving the technical difficulties the customers face with their products or services. Moreover, the tech support employees maintain, manage, and repair the IT faults. They are also responsible for resolving the network problems, installing and configuring hardware and software.

Here's how application test engineers use technical support:

Provide technical support for issues resolution with requirements, software development and product team as needed.
Implemented, tested, troubleshot and performed technical support during launch of data services.

9. Test Scripts

Test scripts validate the quality of the software or app being tested. An effective test script has all the steps to be taken to use a software program as well as the ending result of each step.

Here's how application test engineers use test scripts:

Create automated test scripts using Unified Functional Testing (UFT) and for regression and functional tests.
Involved in developing test scripts for Manual and Automated Testing using Win runner and Test Director.

10. Regression

Here's how application test engineers use regression:

Created module test program for manufacturing, improving product yields based on defect reduction and root cause analysis efforts.

13. QA

QA, or Quality Assurance is a procedure that entails all of the steps taken to avoid any errors in the manufacturing process or in the production of the goods that a company produces. It can also include ensuring the consistency of the services rendered. Quality assurance ensures that the quality of the service delivered to consumers meets or exceeds the promised expectations. This greatly aids in the prevention of any complications that might arise after the goods or services have been distributed. It makes sure that customers are satisfied.

Here's how application test engineers use qa:

What skills help Application Test Engineers find jobs?

Tell us what job you are looking for, we’ll show you what skills employers want.

What skills stand out on application test engineer resumes?

Travis Mandel Ph.D.

Assistant Professor, University of Hawaii at Hilo

The number one thing that employers typically look for is a project that demonstrates your ability to program something new and useful. The best projects are ones that someone undertakes independently or with a small group of others - if it is the latter, you need to clarify what you contributed. It's even better if you include a link to public code on Github so that employers can look around your Github page and get a sense of your coding style. A working demo is also very impressive. Ideally, this wouldn't be something you were forced to do for a class but rather something you took the independent initiative to do.

College GPA doesn't matter as much as people think it does - most companies care much more about what you can do than how well you did in class. Unless it is extremely low, it shouldn't be a problem. Listing courses can be useful, but even better would be listing skills you learned in classes. For instance, the class "Artificial Intelligence" means completely different things at institutions. So employers may not necessarily understand what skills you learned in that class unless you highlight them.

What soft skills should all application test engineers possess?

Travis Mandel Ph.D.

Assistant Professor, University of Hawaii at Hilo

Although computer science seems like a highly technical field, soft skills are really what differentiates software engineers. One of the most important qualities of any software engineer is explaining their code clearly at various levels of technical depth and explaining why certain design decisions were made. You could write code that does amazing things, but if that code consists of snippets you pasted from StackOverflow without really fully understanding them, it will be a huge headache for anyone who needs to come into the codebase later and maintain or update it.

Another one is asking the right questions. Imagine you are dropped into a huge codebase and asked to add a new feature (very common!). There's no time to understand everything that is going on, but on the other hand, you need to understand enough of the code to do your task effectively, which involves asking questions. A failure to ask questions will likely result in you wasting a huge amount of time working on something that is ultimately not useful, for instance, re-implementing a complex function that already exists somewhere in the codebase.
