What is manual testing?

Transmission software testing is when homo testers bank check the quality of a new awarding without using automation tools or scripting. The purpose is to place bugs or defects, ensure the production is error-free, and cheque it conforms to specified functional requirements.

The procedure compares the beliefs of a software application (or one of its components or features) with the expected behavior which was defined in the initial phases of the software development life cycle (SDLC).

Manual testers design test cases or scenarios with 100 percent exam coverage, and execute them one by one before verifying the results. They ensure that any reported issues are passed to the development team to fix, and then tested once again.

One of the key principles of software testing is that 100 percent test automation is not possible—so manual testing is an essential office of your quality assurance process.

What is a manual testing example?

Manual testing has many real-life applications, and is peculiarly handy for assessing usability and accessibility. For example, if you lot were launching an ecommerce website, y'all would demand to check things like:

• Optimization for a range of browsers and devices
• Smooth checkout procedure
• Fast-loading hi-res images
• Links to social media channels

Under manual testing, testers would check the codes that bulldoze each of these functions to ensure they work as the client intends. Manual testers are likewise able to annotate on the look and feel of the website, evaluating it from the user'due south perspective.

Manual testing and automation testing: what's the difference?

Basically, manual testing requires human being intervention, while automation testing uses machines to execute test cases automatically. Any type of application can be tested manually, but transmission testing is especially suitable for assessing user interfaces (UI) and user experience (UX), and for ad-hoc or exploratory testing.

Automation testing is recommended only for stable systems which are likely to have fewer bugs, and is mostly used for regression testing and performance testing. Testing tools like JMeter and Selenium are commonly used.

The pros and cons of manual testing

Although transmission testing is essential if you want to iron out the highest number of bugs, in that location are some downsides as well every bit plus points. Nosotros'll take you through the main pros and cons, then you lot can encounter some of the challenges and rewards associated with using this methodology.

The pros of manual testing

1.  Authentic

Automated tools are smart, just they're non as smart every bit humans. There are sure things that only a real person with real-world experience can spot. So when information technology comes to identifying bugs and glitches in software, manual testing is more than likely to catch 'em all.

2.   Gives human insight

Manual software testers bring a valuable human perspective as well every bit accuracy, by focusing on the expect and feel of a production. They can evaluate the application's visual components and highlight UI and UX problems past adopting the mindset of the stop user.

iii.   Adjustable

The manual method is specially useful in advertising-hoc testing, as information technology's easily adaptable when unplanned changes are made to software. The human input means test cases can be redesigned or tweaked with relative ease. Manual testing is also agile enough to exist performed on all kinds of applications.

4.   Saves money

Although transmission testing requires skilled labor, it can actually save your company money as information technology doesn't need any expensive tools. Automation tools can exist costly to install and volition take time to ready upward and learn.

The cons of manual testing

1.   Resource-heavy

Manual testing is undeniably more time-consuming than automation, which means the testing process is slower and tin sometimes be more costly. It also requires a large number of homo resources, with testers requiring loftier analytical and creative skills.

two.  Not always suitable

Certain types of testing, such as performance and load testing, are not suited to manual methods. For example, humans cannot simulate a large number of users for a operation test in the way a car could. Large amounts of examination data, too, are more efficiently handled by automation.

3.  Potential for error

This is the flipside to #1 in the "pros" cavalcade. Humans are smarter than machines in many means, but they're also prone to human error. Since manual testing is repetitive and boring, it's possible for testers to lose concentration and miss something.

4.  Non reusable

As the manual testing process tin't exist recorded, manual tests are not reusable—you'll need to develop carve up test cases for each new application. It'due south much easier to do this in automated testing where the scripts are reusable.

Types of manual testing

Transmission testing has many variations, with different types suited to different software and environments. Allow's accept a look at some of the most commonly-used manual testing techniques.

Credence Testing

User Acceptance Testing (UAT) is performed by the client or cease-user, to confirm that the software meets the agreed requirements. Sometimes chosen pre-production testing, information technology takes identify during the concluding phase before releasing the product to marketplace.

UAT is an example of functional testing and types of acceptance testing include Alpha (executed within the organization) and Beta (where the application is released to a limited market to generate user feedback).

Blackness Box Testing

Also known every bit behavioral testing, this method aims to clarify an awarding's functionality from the end-user'southward perspective. The internal code construction is non visible during testing (hence the proper noun "Black Box"), so testers are only aware of the inputs and expected outputs of the software.

Black Box Testing has several subdivisions, including functional testing for requirement compliance, smoke testing to assess basic functionality, and partitioning (dividing software into groups that are expected to exhibit similar beliefs).

Integration Testing

Integration Testing is the process of testing an application with two or more than integrating components. It is performed in one case the individual components have been unit-tested, and aims to identify bug with the interfaces and the interactions between them.

The 2 main methods are the Bottom-Upward Arroyo (moving steadily from the lesser module to the top module) and Elevation-Down Approach (the opposite).

System Testing

System Testing ways testing the organisation as a whole, once all its components have been unit-tested and integrated. It checks that the complete application works as intended, by comparing it confronting the original requirements.

Also chosen stop-to-end testing, it typically involves installability testing (does the software install correctly?) and recovery testing (can the application recover from hardware crashes and network failures?).

Unit of measurement Testing

This is when the individual units or components of an application's source code are tested, to make sure each function performs as expected. It is usually carried out past developers rather than engineers, as it requires detailed knowledge of the internal program blueprint and code.

Also known as module testing or component testing, it simplifies the debugging organization and helps to observe and protect confronting bugs in the future.

White Box Testing

Sometimes called transparent box testing or structural testing, this is a method of testing the internal structures or workings of an application. It is performed past the developer, who checks the software'southward internal codes before passing it to a exam engineer.

The primary focus of White Box Testing is on strengthening security and improving the software'south design and usability. A combination of Blackness Box and White Box testing is known equally Gray Box Testing.

How manual testing is performed

Nosotros've already seen that there are several types of manual testing, just the overall testing process is common to all of them. Sometimes this will be carried out in-house, while some businesses prefer to appoint an expert company to handle testing.

At that place are roughly six basic stages in performing manual testing:

one.   Understand requirements

The first thing testers need to do is to fully understand the projection's requirements. What does the client look from the application? What problem is information technology aiming to solve for finish-users? Testers must clarify all requirement documents in order to recognize the expected behavior of the software and exactly what needs to be tested.

2.   Prepare test cases

In one case the requirements are understood, testers tin can typhoon test cases to embrace various scenarios, such equally what happens when a user enters an invalid password or how the software would cope with a crash. These test plans volition set out a sequence for testing functionality and usability across the entire awarding, measured confronting expected results.

3.   Review exam cases

It's helpful to review the typhoon test cases with team leaders and the customer, to cheque that they will cover all bases and make any amendments before commencing the execution. This will save fourth dimension in the long run.

4.  Execute examination cases

Manual testing tin now exist carried out, using whatsoever of the techniques listed in the previous section. As well every bit finding bugs, the aim is to identify potential pain points for users and loopholes that could be exploited past hackers. Testers execute the test cases i by 1, sometimes using bug-tracking tools like Jira.

v.   Study bugs

When bugs are identified, the testing team volition laissez passer the metrics to the evolution team in the form of a examination study. This contains details on how many defects or bugs were establish, how many exam cases failed, and which need to exist re-run.

6.   Examination again

Once the development squad has stock-still the bugs, the software is handed back to the testers. They carry out the exam cases again to check that the problem is resolved.

Combine transmission and automated testing

Although automation is a time-saver, manual testing remains a vital part of software development. Human being testers can remember similar an end-user, and imagine multiple test scenarios for an awarding or function.

Information technology'due south worth remembering that while software testing attempts to find as many bugs as possible, identifying all possible defects is literally impossible. Manual testers can often spot issues that a machine could overlook, but they are also susceptible to human being error.

Using a combination of transmission and automated testing is the virtually effective way to catch the highest number of bugs and defects. Experts like Global App Testing offer the best of both worlds—contact our team  to learn more than and chat with a friendly agent.
