It comes at a time when a software tester is at crossroads wondering what kind of testing would be most appropriate to use. Manual testing and automatic testing both serve to test a software and rid it of any resulting bugs or defects ensuring that a product is market-ready. Various experts prefer the two types of testing due to their characteristics as is described throughout this article. They each bear advantages that make them preferable in different situations. Software testing will require either of the two types of testing depending on different factors. These factors range from budget issues to quality requirements of the software. Time allocated for testing is also a major factor when choosing the type of testing to use. The two types of testing all bear a number of advantages and disadvantages that are all best understood by Quality Assurance (QA) testers. This features of the individual testing type are what enables an informed decision of what type of testing is required for a software test. This article will serve to provide information on both of the two types of testing to allow for the ease of choice in all matters of software testing.
Manual testing as the name states is the testing that is done manually without the use of any testing scripts or tools. It is executed by a human who has to manually check various components like performance, design, and functionality by testing the various areas related to the components. Defects are determined if there are disparities between the desired and actual results from the test.
Advantages of Manual Testing
- It provides a quality and efficient check of defects that would have otherwise been overlooked by automated testing.
- It results in improved customer experience and a better graphic user interface since it allows for human observation which can then be edited to the desired result.
Disadvantages of Manual Testing
- It is redundant when used for test cases that have frequent repetition. Therefore, it is very inefficient for software that has frequent code upgrades.
- It is liable to suffer from human error since the whole test is conducted by a human being and may thus be affected by issues of inaccuracy.
- It is time-consuming to test each and every component manually and may prove to be a boring task for the testers involved especially if the software being tested has frequent code upgrades.
Cases where manual testing is preferred
- Ad hoc testing: this is the testing that is done on an impromptu notice. It lacks any plan or approach towards the testing. It requires manual testing so that each component can then be individually tested.
- User Interface (UI) testing: this is where a software is tested on its ability to be user-friendly. Such a test requires a human being to act as an end tester to ensure that the software user interface is acceptable. Factors like colors, fonts, links and images are best done using manual testing compared to automated testing.
- Exploratory testing: this is a test that requires the tester’s knowledge and expertise of the software. It is also a result of a project being given a short time window for testing. As a result, automated testing cannot be used as the automation testing tools require a lot of time and resources to assemble and execute them. Therefore, manual testing becomes the only option.
- Testing of software that can’t be automatically tested: some software can’t be automatically tested especially if they are related to hardware. This software with the example of sensors provides a difficult time when code or script is written for them. The script over time also becomes non-viable and thus manual testing remains the most viable option for testing.
This is a test that requires the assistance of automation tools, software, and scripts in order to allow for testing. These tools, scripts, and software help the Quality Access tester to test parts of the project in detail with more ease compared to manual testing. Some of the common automated testing tools include Selenium and TestingWhiz.
Advantages of Automatic Testing
- Automatic testing is more reliable because the tools and software used, provide more accuracy compared to human testing.
- Automatic testing provides a high speed of execution which enables for testing to be done quicker than manual testing.
- It reduces expenses in the long run since the automation tools can be reused for various testing projects.
- Automation testing is more comprehensive as it covers more areas for testing in a software.
- Automation testing provides an option to upgrade the testing areas as it has a feature of programmability.
- It also is time-saving and allows for repetitive functions of a software.
Disadvantages of Automatic Testing
- There is a lack of human observation and therefore some features are bound to be redone using manual testing. An example is the graphical user interface that requires a human being as an end user tester.
- Automatic testing can be viewed as expensive since the acquiring of the tools whether by purchasing or writing requires a lot of resources. These expenses add up as new testing areas are encountered since new tools are supposed to be acquired. If a failure is encountered during the use of the automated tools, an expert, and complex analysis is required which may prove to be expensive.
- There is a difficulty in maintaining the test data files.
Cases where Automatic Testing holds preference.
- When a project is composed of repetitive tasks. Here, the automatic testing provides an ability to test the tasks without tiring as would have been experienced with manual testing.
- Performance testing: automation testing provides reliability which will ensure that the performance of a software is assured.
- Regression testing: this is a test that ensures a change in the code does not affect the already existing properties of a software.
- Advanced Graphical User Interface testing: automated testing can be used to test the differences between various types of platforms under test.
Testing is a very vital procedure that cannot be avoided in the process of developing a software. It is a key step that cannot be ignored or taken lightly. Manual and automation testing while having varied differences are more often than not co-dependent on each other. There is no type of testing that can definitely be declared as superior compared to the other as they both serve to provide functionalities complementary to each other. Therefore, whether you are a novice or an expert in the field of testing, you need to know what you are trying to achieve so as to be able to pick the right type of testing for you.
