The best testing strategy : Apps for financial calculator

Different types of software require different types of design, standards, and architectures. In this blog, we’ll look at some of the crucial things that define a strategy for testing and apps for financial calculators. The application which we develop for the use in financial sectors generally needs to meet very strict and well-defined requirements. They also need to deal with legal factors under which financial institutions must operate. As they control the money of the customers. So while testing we need to consider all of these standards, along with the basic functional requirements of financial application software.

Applications for Testing

Below are the applications for testing:


Financial application testing software and systems that store financial data are among the main targets of the most sophisticated cybercriminal operations.

If criminals gain access to customer and transaction records or applications, they can use them illegally for fraudulent activities such as withdrawing or embezzling funds, creating fake money laundering accounts, or changing records to hide transaction details. In effect, they can steal individual customers or financial institutions with almost perfect anonymity and virtually no physical risk.


Financial applications must process and store transaction data reliably and accurately. They must also have a very high level of transparency. Although many of the elements that contribute to this type of basic reliability are relatively easy to program and test, not many of them are reliable.

Regulatory compliance

As mentioned in the beginning, virtually all financial software must meet the requirements of one or more regulatory agencies. Very often, a google financial app application must follow the various regulator’s standards that operate under the authority of different regional or national governments. Compliance can be extremely important. Failure to comply can, in some cases, result in civil, financial, or even criminal penalties for organizations or individuals held responsibly.

High volume of Performance

Financial applications generally handle a very high volume of transactions and need to process them very quickly. This is true for customer-oriented software in areas such as consumer banking, digital wallets, online loan processing, and point-of-sale transactions; including those that are non-consumer applications, such as those dealing with commercial stocks, commodities, or derivatives. Automated transactions in these areas can occur at a very high volume and can require extraordinary speed and accuracy of time.


The workflows involved in financial and banking software can be extremely complex and individual applications can be closely integrated. With a large number of other programs, all of which may be dealing with a huge number of transactions. When you combine this general complexity with the need for validation, reporting, and auditing and the real-time nature of many of the interactions, the real level of complexity is even greater.

The best testing strategies

Following are some of the best testing strategies:

Take care of the basics first

As always, your test regime should cover basic functionality and performance. This includes the very obvious functional problems (user interface, input, output, and storage) and features that, by all rights, should not be a problem, given the basic nature of the software, this includes items such as computational accuracy. You cannot assume that simply because you are testing a review of an existing app for financial planning, there is no need to check the math.

A change in code in one part of the program can have an unforeseen effect on something as simple and unrelated as arithmetic calculations in another part of the program. In the case of financial software, the cost of a bug can be extremely high. The same applies to obvious mistakes for beginners, as the unmanaged buffer overflows. It is never worth neglecting the basics!

Attention to business requirements

You must create a set of acceptance criteria that could be next to your test cases, based on the requirements of the application. In the case of financial software, it is important to work closely with product, business, and client-side professionals. To ensure that these scenarios accurately and completely address how the software will be used.

Use cases that are/which involve:

  1. The most common types of transactions
  2. Scenarios that emphasize application more
  3. Time-sensitive transactions
  4. Transactions that involve the greatest risk or potential damage

In addition to functional testing, apps for financial planning must be tested for operation under heavy loads and conditions that place a high degree of stress on the software and its infrastructure.

Note that the load and stress tests are not the same. The load test looks at how the application handles a very large volume of transactions. And associated operations, such as database reads and writes. Stress testing, on the other hand, focuses more on how the application handles a high volume of transactions over an extended period. It can detect cumulative problems, such as memory creep, that may not be apparent in a simple load test.

Testing security holes

Needless to say, testing security issues is crucial. You must assume that the application you are testing will be under constant attack by professional criminals, who will try to exploit any vulnerability found, at a potentially extremely high cost for users of the application, even more so in the current “era of benefits”. You cannot assume that adequate security is already built into the software, but it is better (and more realistic) to assume that the software contains undetected vulnerabilities and that it is your job to find them.

Given the number of high-profile data breaches reported in the news, it is clear that proper security testing and programming is not always the norm. The security tests you perform can be crucial to the privacy, financial security, and retention of your business customers. As always, the breadth, depth, and scope of the tests are crucial. Automated parallel tests generally offer the best and widest detailed coverage, mainly for load, stress, and safety tests. Financial testing software requires a well thought out strategy. And with the right testing tools and infrastructure, it can be a lifesaver for us and our customers.
