Software testing for absolute beginners

What is software testing? 

Software testing is one of the important activities that are carried out to test particular software for its efficiency. Software testing is generally done by organizations to validate if the software is developed as per the user requirement and it functions as accurately. To learn software testing you needs to enroll for a software testing course.

Imagine you decide to purchase a brand new car in a red color. But the dealer gives you a car which is in blue and it’s dirty, or maybe while driving the gears and the clutch does not function properly how frustrated would you feel. This can result in customer dissatisfaction and loss of business. Software testing helps you avoid taking such a big risk. The software tester’s job after completing software testing course is to verify the customer’s requirement and check if the software matches his requirement.

Also, he needs to check if the software functions properly as if the customer faces issues while operation he would be frustrated. He rigorously checks the software without any mercy on the bugs. In software testing course he is taught to finds them from every nook and corner and makes a note of it making sure the errors are fixed.

Types of Software Testing: 

Software testing is broadly divided into 3 categories which are covered in software testing course is: 

1. Functional Testing
2. Non-Functional Testing or Performance Testing
3. Maintenance Testing 

Let’s look at each one of them respectively.   

1. Functional Testing: This type of testing is one of testing where the software or the system is tested against the functional specifications. Now the software tester makes sure that he checks the functions provided in the software. He tried to check if the input given in the software provides the right output. Sometimes the user can enter wrong input so the tester checks if there is any validation for such wrong input. The tester also makes sure he prepares and executes test cases to conclude. If there is an issue the tester communicates the same with the development team so they can make the required changes.  

   

   
   
2. Non Functional Testing: The non-functional software testing is opposite to functional testing. Here the tester checks the performance, readability, and usability of the software. It is mostly done to make sure the software performs well in the production environment. On the production floor, there is a lot of processing going on at a single time. If multiple users use this software continuously there are chances it may crash. To avoid this, non-functional testing is done. This show tells us if the software can handle the load at a time. 

 3. Maintenance Testing: This is the last but very important type of testing. Once the software has been implemented in the production environment then the software can need an upgrade. This upgrade can be required if the user upgrades to different operating software or hardware. The software is tested for any upgrades and issues in this level of testing.

Software testing has become a vital part of the IT field. Imagine without software testers how would the software industry progress.

What you should know about Java Programming?

Introduction:

Java programming is the best object-oriented programming language. The reason being, Java programming is widely used in every machinery. The coding in Java is clean and precise. There are too many new programming languages that are based on Java programming language. If you learn Java it is a way to easy for you to learn other programming languages.  Java was first introduced by Sun Microsystems. Later on, this language started gaining popularity. If you want to learn Java programming you need to enroll for Java courses in Pune. This course will provide you detailed knowledge of Java programming also will provide you with hands-on experience.

Why is Java so popular?

Java programming gained its popularity just a few years later from when it was launched. There were few features that Java offered and other programming languages like C did not offer. These features not only made coding easy but effective and precise. Let’s discuss some features of why Java became so popular.

1. Object oriented programming: Unlike C which was a procedural language, Java was based on an object-oriented programming concept. In C there was a pain which Java addressed and made its mark in the market. C programming was wrote as per the sequence by which program should perform, and if we needed to perform a same function next time we needed to again enter the code which increased redundancy. Java eliminated it by using objects which can be written in any way and the sequence can be decided later and the same function can be called without having to write the code again which saved execution time.
2. Easy to use: Unlike other programming languages, Java is easy to use and to learn. This feature of Java makes it a popular programming language.
3. Security: If you consider security in Java is much higher than C programming. This language was made secure for the sole reason that it was originally developed for mobile devices and was being used to exchange data over networks. If the language was not secure the data would be leaked.
4. Platform independent: Java programming does not require a specific operating system to work it can work independently on any platform. It achieves this with JVM (Java Virtual Machine), this is a virtual environment created by Java so the programs can be executed.

In order to learn Java programming, you need to enroll for the Java certification course. This course helps you to get the best knowledge and 100% placement guarantee. Learning Java programming can help you learn other programming languages. To enroll for our Java programming course visit our website www.exltech.in or call us at 9607905150.
