What is Use Case Testing and How to Prepare a Test Case for Testing?

In the phases and life cycle of software development, use case plays an important role. The entire process depends on the actions of the user and the response by the system to the actions. Hence it can be seen as documentation of the actions which is performed by the user or actor and then the corresponding interaction by the system to those actions. Not all the use cases result in achieving the goal by a user to the interactions with the system.

In a use case, the system responds to the situation or behavior. It is user-oriented rather than system-oriented. That is, they are actions that are done by the actor/user and not the output produced by the system. Hence the development team writes the ‘use cases’ as this phase depends on them. The writer of use cases, a team of development, customers, all of them together contribute towards the creation of use cases and testing.

What is Use Case Document?

Use case documentation helps to complete an overview of all the several ways in which the user interacts with the system to achieve the desired objective. The documentation will help to check the requirements for the software system and what is lacking in this process.

Who will use the Use Case Document?

As the documentation helps to get an overview of ways in which users can interact with the system, better documentation is always required for easier results. This documentation will be useful to the software developers and software testers along with the stakeholders.

There are several types of uses for these documents. It helps developers to implement the code and design the same. Further, testers use them to create test cases. Business stakeholders, on other hand, use the documentation in order to understand how the software works and their respective requirements.

Elements in Use Case Testing

The major elements of the use cases are brief introductions which help to explain the case.

1. Actor, that is, the users which are involved in use case actions.
2. Precondition, which is the conditions that need to be satisfied before the case begins.
3. Basic Flow, or the main scenario which is a normal workflow in the system. In other words, this is a flow of transactions done by actors to accomplish their goals.
4. Alternate flow, which is a less common interaction done by an actor with a system
5. Exception flow, which prevents a user from achieving the goal
6. Postconditions that are required to be checked after the case is finished.

How to Prepare Test cases?

It is best if the test cases for the main scenario are written first and then written second for alternate steps. These steps in test cases are from use case documents. Cases are supposed to be required as steps and the user or actor must be able to enter the same. Test design techniques can be used and developed to help reduce the number of test cases which can help reduce the time taken for testing.

Writing test cases and testing is an iterative process. Practice and knowledge of domain and system are required in this case. Using case testing in applications can be used to find missing links and incomplete requirements. Finding and modifying the same will bring efficiency and accuracy into the system domain.

What is software marketing?

The process of creating a market for any software leads to software marketing. Simply put, it is a way to market any software in the digital space for more sales and promotion of software.

Every startup software company uses a variety of methods and techniques to harness the marketing resources available in the digital marketplace.

Each software has its own user goals and benefits. Target customers are also defined according to the software. You cannot market software like other products. There are specific strategies that every startup software company needs to follow. Every company wants to increase its profits. Investing in product marketing increases profits.

There are some rules before you devise a market strategy

• Create your story before you appear
• Set goals before you plan to achieve
• Create an excellent website
• Keep the website SEO friendly
• Email marketing campaigns

Create your story before you appear

There is a story behind every creation and also of your software. Think about your startup and the software you want to market.

Software companies make the mistake of giving too many technical explanations in their communications before the customer understands the operation of the software and what it does.

You need to create and tell a story that explains the idea of ​​software, its functions, what it offers to its customers, and ways to differentiate businesses from competitors.

Set goals before you plan to achieve

Before formulating a marketing strategy, you need to set goals. Why? It is not possible to know success unless the goal is to be achieved.

Setting goals is one way to understand what you want from a marketing strategy. Ask yourself, what are you planning to achieve with the market strategy? Is it to increase sales or to reach more target customers or is it a brand awareness marketing strategy?

Keep the website SEO friendly

You need to try to make your website SEO-friendly. It helps with organic traffic to websites. Visitors coming through organic traffic are mostly your potential customers. Give them what they want.

Email marketing campaigns

Email marketing is one of the best marketing strategies for startups. It helps build a database of potential customers as well as convert potential customers into sales. Drip email leads to sales leads by downloading sequence content or providing trial software links. Offering something for free in an email leads to your website.

Media queries allow you to customize the presentation of your web pages for a specific range of devices like mobile, phone, tablets, desktops, etc. without any change in markups.

Syntax

@media Rule

The @media rule is used to apply a different set of styles for different Media/devices through the use of Media Queries.

Parenthesis

We set the condition inside the parenthesis.

If I want the background color to be changed in the smaller screen, I can set the condition inside parenthesis.

Media Types

If we don't apply a media type, the @media rule selects all types of devices by default.

There are many kinds of devices but we can group them into 4 categories:

all - for all media types print - for printers screen - for computer screens, tablets and smart-phones speech - for screen readers that "read" the page out loud

Breakpoints

Breakpoints are points where the website content responds according to the device width.

This is how the code works

when the screen is 992px or less, the background color is changed to blue from red

some common breakpoints for widths of devices:

• 320px-480px: Mobile devices
• 481-768px: iPads, Tablets
• 769px-1024px: Small Screens, Laptops
• 1025px - 1200px: Desktops, Large Screens
• 1201px and more: Extra Large Screens , TV

SaaS testing is the process of conducting a test case on an on-demand software or web-based software system. Software testing as a service is different from testing on-premises applications because SaaS-based application testing requires access to browsers and is centered around web application testing methods.

The software tests robust SaaS performance testing plans against real-world traffic in a cloud environment to confirm that the service is available, useful, and optimized for all web concurrent users at all times. By adhering to the best practices of SaaS testing, your team can quickly deploy updates and upgrades, increase ROI, and increase user satisfaction.

SaaS-Based Solutions: 4 Reasons to Testing

Reason 1. Smart scalability

The option to change software capabilities immediately upon request allows tenants to save costs on using cloud services. What's more, SaaS vendors use auto-scaling mechanisms that diagnose the amount of current users and adjust the software according to sizing needs.

Reason 2. Regular and rapid updates

Within the tight relationship with the SAS provider, the shortcomings and modifications of all solutions go through it. As a rule, the process of correcting errors and making changes is quick and frequent. Therefore, a robust QA strategy should be defined to optimize the snowfall of test scenarios on short notice.

Reason 3. Multi-tenancy

SaaS opportunities to use shared cloud resources make it affordable for a range of different organizations and streamline software support. Within the approach of providing access to multiple customers, each tenant's data is different and remains invisible to other subscribers. However, the sheer number of connections with a vendor can cause difficulties in compatibility and integration. In this case, improving the quality of the API may be the escape solution.

Reason 4. Adjustable architecture

One more reason why companies choose SaaS is the ability to customize and specify settings that perfectly match the needs of the business. And this requires thorough supervision, as improper operation of the IT solution can lead to defects after adding some modifications that can exacerbate the increased churning rate.

Therefore, in these specifications, SaaS testing is more complex than testing cloud and on-premises apps, which gathers more demand and a more in-depth attitude towards QA activities.

Now Let's see main points to get Upscale SaaS-Based Solutions

1. Functional testing

Testing all levels of connections between IT product components, including units, their integration and system testing, QA experts check the proper management of efficiency. Notably, the general requirements include numerous cases corresponding to casual user scenarios. Checking numerous configuration combinations makes testing more complete.

2. Performance testing

While on-premises applications are based on the user's environment, the customer experience in SaaS-based products may be influenced by others. Thus, performance checks are necessary - to run stress and load tests, QA engineers identify the above limitations of software capability and evaluate its behavior under the expected number of concomitant users.

3. Interoperability testing

SaaS based products perform flawlessly against various browsers and platforms as a prerequisite. Before conducting the interoperability test, the QA team estimates the most preferred browsers and platforms and isolates the browsers used by a few clients to exclude them. With every browser or platform tested, QA specialists cover the full scope of test configuration and provide seamless software operation for a wide range of users.

4. Usability testing

Intending to reduce churn rates and build long-term relationships with end users, companies primarily strive to enhance the customer experience with convenient app usage. By providing simple information architecture, simple workflow and interaction as well as visual readability and adequate feedback on commonly used functions, the individual can satisfy customers through a user-friendly application.

5. Security testing

Within sensitive data, SaaS-based solutions need to enable highly secure storage and disposal of information. Accepting casual accounts and roles, these applications require full validation of access control. To identify vulnerabilities and avoid data breaches, QA experts perform penetration testing, exploring potential barriers.

6. Compliance with requirements

Winning the competition also assumes meeting worldwide standards. Depending on the industry, HIPAA checklists for health products, OWASP security recommendations for any-domain web and mobile applications, GDPR to enable secure data storage and worldwide transfers and much more may be required to conduct software testing.

7. API testing

API testing is required between organizations delivering SaaS products, in conjunction with customer platforms and other third-party solutions. With it, instead of using default user inputs and outputs, QA engineers run positive and negative views of calls on APIs and analyze responses to system interactions. Such an approach allows in advance to ensure that the API application and the calling solution work properly. It focuses primarily on the business logic layer of software architecture.

8. Regression testing

Once the new functionality is implemented, it needs to be verified that the latest improvements have not affected the developed features. Being an elaborate and cumbersome process, the SaaS regression test includes all the test types mentioned above and a range of test cases involving more.

InfyOm has experience delivering comprehensive QA assistance with solid regression testing. Learn how our QA engineers tested and streamlined the software, ensuring the quality of the SaaS platform for public housing authorities.

Summary

Once you decide to build a true bug-free SaaS application, IT strategy needs to add SaaS testing to its specifications that include the use of Wise Cloud resources, prompt updates, multi-tenancy and customization.

By introducing QA tips from the InfyOm list, one can improve the quality of solutions, obtain the required business and operational values, and reduce churning rates.
