Computer software and mobile applications are programs designed from a suite of binary instructions. Depending on the needs, the developer uses different programming languages such as C #, SQL, Java, Python, PHP, HTML, etc. For a computer program to work perfectly, there should be no errors in the command lines. It is these code errors that generate the software bugs.

Project Infer: automatic bug detector
A mobile application should never be launched on the market as long as there is a risk of bugs in the program. In the pre-launch process of an IT product, the software should undergo a series of tests integrating all possible use cases. Unfortunately, the risk of code combinations that generates a bug still exists despite these series of validation tests. Project Infer analyzes mobile application codes and looks for possible error conditions. The developer will only take care of the verifications afterwards.
Interference logic
The Project Infer solution uses inference logic to analyze the potential code executions of an application. It produces additional knowledge about an application. It consequently increases the efficiency of the application throughout the development stages. Project Infer follows a workflow split into two main phases: capture and analysis. During the capture phase, Project Infer converts the programming codes by another internal code of its own. In the analysis phase, the tool explores each method, function or procedure and detects possible error conditions. If Project Infer encounters an error during its analysis, it stops the execution at this level, but on the other hand continues the analysis of the other methods.
The logic of separation and the double removal
Mathematics is involved in the way Project Infer works: the techniques of separation logic and double removal are required. Compared to the separation logic, Infer scans the program only on a small part independent of the application’s storage instead of considering all of the memory. Double removal automates key ideas about local reasoning. Its objectives are to allow the framework to discover the properties of parties independent of the programming code.
