 \subsection{Testing}
+\begin{itemize}
+  \item Testing can be run with Gradle when it comes to running unit tests
+  \item Decided to use JUnit 5 as it provides additional tools such as
+    statistics, integration with IntelliJ to view code coverage,
+    or being run in continuous integration tests
+  \item The testable components in this project is mostly backend modules as
+    the GUI made in Compose is not the focus of the project and it would
+    require a lot of extra time
+  \item Unit tests have been made for the database and Koin
+  \item Koin comes with tests that can be automatically be generated
+  \item Ethos when testing was to try and find exploits, act as a
+    user who may mishandle inputs, and stress testing functions
+    by passing parameter with hundreds of objects
+\end{itemize}
 
+\subsubsection{Testing for Resource Usage}
+\begin{itemize}
+  \item The application was tested using the \textit{Profiler} tool on
+    IntelliJ IDEA 2024 (Ultimate Edition) to find potential
+    memory leaks
+  \item One problem found was the initial VDMJ wrapper which would use the execute
+    command instead of the interpreter, which would require reinitializing
+    the entirety of VDMJ, which resulted in a slight memory leak and a
+    massive write usage
