In software testing, anomaly reports are crucial for identifying unexpected behaviors or discrepancies in the software application. Anomalies can be in the form of bugs, errors, crashes, or glitches that occur when the software does not function according to the requirements, design specifications, or user expectations.
Software applications often encounter unexpected behaviors during testing, which can delay the identification and resolution of issues. However, using an anomaly report in software testing processes helps you ensure systematic documentation and quicker identification of these issues (discrepancies) to maintain software quality.
In this blog, we look at what are anomaly reports in software testing.
An anomaly report, also known as a bug or defect report, is a document created during the software testing process to identify and report issues found in a software application. It acts as a medium that provides stakeholders with the necessary information about the detected anomalies.
Anomaly reports provide details about how the issue was discovered and the environment in which it occurred. They include steps to reproduce the issue and highlight the difference between expected and actual results. By using this report, you can gain a clear understanding of the issue, enabling them to implement the necessary changes or fixes in the software application.
Each report contains all relevant details about the issue, including its source, actions required for resolution, and the expected result. This information allows you to analyze and address the issue efficiently.
An anomaly report in software testing keeps the information in an organized format to record and track issues effectively. The key components of the anomaly report are as follows:

Data flow anomalies are programming errors identified during software testing, especially during white and black-box testing techniques. These anomalies are often detected when reviewing the data flow of data within the software during the execution of the program. The anomalies are represented using a combination of three letters: d, u and k.
Below is a table that shows the possible combinations of these letters, along with their descriptions and consequences:
| Combination | Description | Consequence |
|---|---|---|
| dd | Defines a data object repeatedly. | Non-critical, but it may lead to vulnerabilities or redundant code. |
| dk | IDefines a data object and then kills it without using it. | Can be a defect, often due to poor programming logic. |
| du | Defines a data object and then uses it. | No issue with this combination, as it is the correct sequence of actions. |
| kd | Kills a data object and then redefines it. | No issue with this combination, as it is a normal occurrence in some cases. |
| kk | Kills a data object repeatedly. | Generally Non-critical but may indicate a bug or defect due to unnecessary actions. |
| ku | Kills a data object and then uses it. | Can be a defect, as the object is killed and should not be used afterward. |
| ud | Uses a data object and then redefines it. | No issue with this combination, as it is a valid sequence of operations. |
| uk | Uses a data object and then kills it. | No issue with this combination, as it represents a valid flow of actions. |
| uu | Uses a data object repeatedly. | No issue with this unless the object is meant to change state. |
The above combinations help in identifying logical errors in the way data objects are handled within the software. Some combinations (like du or kd) are considered valid and non-critical, while others, such as ku (killing a data object and then using it), indicate potential issues that need to be addressed.
Data flow anomalies are crucial in pinpointing issues related to the data’s life cycle in the software application. They help you ensure that your code functions correctly without any issues.
Artificial intelligence enhances anomaly detection and reporting in software testing by:
You can use various AI-powered or AI-native testing platforms that can significantly improve the efficiency and effectiveness of your anomaly reporting.
For example, AI-native test execution such as TestMu AI offers the Test Intelligence platform that comes with AI-native features to streamline the detection and management of anomalies:
Some of them are:
Additionally, you can also harness the potential of TestMu AI Insights to assess high-impact quality issues with detailed test observability and analytics suite.

Moreover, for anomaly detection, you can leverage KaneAI by TestMu AI. It is a GenAI native QA Agent-as-a-Service platform for high-speed quality engineering teams to generate, evolve and debug tests using natural language commands.
KaneAI helps you with bug identification and auto-healing by automatically identifying them during automated test execution. You can also reproduce and fix the issue by manually interacting, editing or deleting the test steps.
With the rise of AI in testing, its crucial to stay competitive by upskilling or polishing your skillsets. The KaneAI Certification proves your hands-on AI testing skills and positions you as a future-ready, high-value QA professional.
When reporting anomalies, it’s important to follow certain best practices to ensure the issue is communicated clearly and resolved quickly.
These practices help you understand the issue and work toward its resolution:
A collaborative approach ensures that anomalies are resolved faster and with better solutions. You should communicate regularly to verify whether the issue has been resolved and to clarify any details that may arise during the debugging process.

In this blog, we explored the importance of an anomaly report in software testing. Anomaly reports help identify issues or defects in the software application. By clearly documenting these issues, you can understand them faster and work together to fix them.
This further enhances the software application and ensures it works as intended. We also discussed some best practices for writing good anomaly reports, such as being clear and providing all the necessary details. Following these tips helps you ensure the software is thoroughly tested and functions as expected.
