You should click into File, after which you can redirect to New. Now, you need to click on New Project. After this, you will be redirected to choose Project Template.

Activity indicates the screen of the application. Hence, if the project features No Activity, it is going to be totally empty, in addition to the basic file structure. 

The basic activity involves the creation of the starting application for the application, which will be adding the button at the bottom, whereas the hamburger menu is present at the top.

It is recommended to select the package name and name for the latest application. This name is what the potential users view the installation of the application on the device. 

Moreover, the package name refers to the internal reference, which is useful by the Android platform so that you can differentiate it from different applications.

After this, it is necessary to decide where you require the files to be saved. Moreover, you need to decide the language in which you want to do coding. Kotlin and Java are the primary languages where you can perform the coding.

Kotlin vs. Java

A primary decision you should take to create mobile applications is choosing from Java or Kotlin. Both Android Studio and Google offer support to both languages officially. 

Google offers support to Java, which the developers use in creating Android Applications for several years. Java has earned high popularity as a widely popular programming language. Hence, it is referred to as an excellent option for people who want to start mobile application development.

Kotlin contributes to being a popular choice of Google to execute Android development. It is considered to be the default to begin the development of the new application. Kotlin is regarded as the popular choice for the end-users, who are a beginner in mobile Application development.

Hence, Kotlin is regarded as the proper language, which is recommended for Android developers. Besides this, you should take the Minimum SDK into account.

Boundary Value analysis contributes to being a software testing technique that involves testing different boundary values of different invalid and valid portions. The behavior at every equivalence portion's edge is more incorrect compared to the behavior present in the partition. 

Hence, boundaries are recognized as an area in which software testing will produce errors and defects. 

It is referred to be a black box technique, meant to detect different errors and bugs at the input domain boundaries. 

So, this type of testing's primary idea is choosing the input variable values at its minimum.

Two boundaries are present at every range, which include the upper boundary and the lower boundary. 

The valid partition's boundary value is referred to as the valid boundary value. On the other hand, the invalid partition's boundary value is known as the invalid boundary value. This type of testing is meant to cover the invalid and valid boundary value.

If you want to design the specific test case for such testing, it is recommended to select the test for every boundary value. There are scopes of applying the boundary value analysis at different test levels.

What is boundary value analysis?

Studies reveal that majority of the errors take place at the boundary values. It is recognized to be an indispensable part of Equivalence partitioning. 

In this kind of software testing, different test cases are chosen at the equivalence classes' borders. 

Such type of testing stands out of the ordinary in enhancing software testing's effectiveness and efficiency. 

The test cases are created, following a strategy that can be modified easily, even if minor changes are necessary. It is possible to extend the minor changes to the project's maintenance phase.

Boundary value analysis has gained prominence as the black box testing process, which is related to equivalence class partitioning closely. Such type of technique involves the analysis of application behavior with the test data, which is present at the equivalence classes' boundary values.

Example

Take the instance of an app that accepts the numeric number. It has the input, having the value, within the range of 10-100. For instance, you should identify equivalence classes, where each of the valid equivalence classes has values between ten and one hundred.

For the specific equivalence class, the boundary value will be 10,100. It is possible to find the edge value of the equivalence classes to generate test data sets to execute boundary value analysis. 

Boundary value analysis effectively finds the errors and defects once the density of different defects at different boundaries is known to be more. The overall time to execute the tests decreases with the reduction of the total count of the test data.

Advantages of boundary value analysis

There are different advantages of boundary value analysis, which are mentioned below:

Decreasing the total count of redundant test cases

If there is a massive input value number, it is not feasible to test every value, ranging from 100-999. It will consume your efforts and time and would go to waste. In this context, constructive test design techniques such as Boundary Value Analysis will be the ideal solution as it stands second to none in reducing the test after every input.

Procuring higher test coverage

At times, it requires the testing of every number virtually for having accomplished test coverage. However, it is not possible at all. The boundary Value Analysis assures the coverage of different test scenarios.

Structuring and standardizing the test cases

At times, as mentioned by different software testers, the test cases are highly dependent on the test case's author as it will not be any standard test case. As you adopt a defined structure, you will be successful in removing the dependency. It provides chances to enhance the software testing standard. Such test cases are known to be highly effective.

Performing quality testing within the stipulated time frame

Time is of high value. It might take several years if you plan to test every possible input value. Hence, it is necessary to design the test cases invariably through boundary value analysis. It offers the suitable choice to complete the software testing while saving your precious time.

Removal of unreliability

It is not possible to execute random testing for crucial applications. It is essential to cover every scenario. 

The test cases should also include covering different logical scenarios if it fails to test every input value. In this aspect, boundary value analysis is recognized as a reliable technique adopted in a plethora of highly successful software testing suite.

As you try to test different boundaries, you will test either of the equivalence partition classes. However, as the output fails, the Boundary Value Analysis will not be sufficient to find whether the application has faults. 

However, the application will work, as it includes the values present between different borders. There are risks that the borders will fail, and vice versa might be true as well. As you test either of the value present in every partition, you will not get the confidence to cover every test scenario.

As mentioned earlier, the boundaries might be an issue. With the implementation of test cases, following Boundary Value Analysis, it is possible to efficiently cover different test scenarios. It helps in saving an ample amount of time. It reduces the need for exhausting testing. A suitable solution to get rid of this is the implementation of such design techniques.

Summary

As the software testing company aims to test a massive app, smart test design techniques are recommended. 

Understanding and performing test cases that are written following the software design techniques like Boundary Value analysis, is beneficial in getting successful software testing. 

Boundary value analysis is considered to be a design strategy for black-box testing. The test boundary conditions involved in boundary value analysis involve testing values from different logically partitioned data classes. Using the boundary value analysis involves designing the test cases that assure the test scenario coverage, which ensures improved quality testing.

Computers are the most important technological invention of this century. The computer as a hardware or a software device was not invented by just one person. Many scientists have contributed in developing this machine. 

In fact the nature as well as the functions of the computer is still not static; it keeps growing with the changing times. 

Professionals in the technology industry keep updating the computer by introducing newer and more sophisticated as well as more improved versions of the computer from time to time. 

As a result we see that new kinds of computer software are being manufactured almost on a daily basis. The rising number of software programs that are being developed has given cause for some alarm to the security testing services authorities. 

As a result testing computer software; especially one that is new and unused is a very important part in the process of manufacturing and selling a computer system.

Since we live in a fiercely competitive world, we are always on the lookout for something that might make our lives easier. The computer is one such thing, add the internet to this list and you will have the perfect combination. 

These two technological inventions have literally revolutionized the way things are done in the present world. Take for example the business world, about a decade or two ago no one would have even imagined that the internet could have been a source of income for many people, especially freelance writers. 

In addition it was also undreamed of that business transaction could be completed in any other way except in the conventional way. There are numerous software products that are used especially by business professionals. Here too, testing computer software before distributing or using it is absolutely important.

Software testing services is an imperative part in the process of manufacturing computers. Since there are various kinds of software products that are being manufactured in the technological market, it is essential that the manufacturers know whether or not the particular software product that they are manufacturing will get them profitable business. 

Therefore, there are two main reasons behind testing computer software. The first reason being that the manufacturer needs to ensure that there are no errors in the software, and if there are any, then they need to be corrected. 

The second reason is to ensure that the software product that is being manufactured will be of an acceptable standard to its target audience. Once these two criteria are covered the product is sealed to be sold.
