+# Static code analysis for FreeRTOS-Cellular-Interface library
+This directory is made for the purpose of statically testing the MISRA C:2012 compliance of FreeRTOS-Cellular-Interface using
+[Synopsys Coverity](https://www.synopsys.com/software-integrity/security-testing/static-analysis-sast.html) static analysis tool.
+To that end, this directory provides a [configuration file](https://github.com/FreeRTOS/FreeRTOS-Cellular-Interface/blob/main/tools/coverity/misra.config) to use when
+building a binary for the tool to analyze.
+
+> **Note**
+For generating the report as outlined below, we have used Coverity version 2018.09.
+
+For details regarding the suppressed violations in the report (which can be generated using the instructions described below), please
+see the [MISRA.md](https://github.com/FreeRTOS/FreeRTOS-Cellular-Interface/blob/main/MISRA.md) file.
+
+## Getting Started
+### Prerequisites
+You can run this on a platform supported by Coverity. The list and other details can be found [here](https://sig-docs.synopsys.com/polaris/topics/c_coverity-compatible-platforms.html).
+To compile and run the Coverity target successfully, you must have the following:
+
+1. CMake version > 3.13.0 (You can check whether you have this by typing `cmake --version`)
+2. GCC compiler
+    - You can see the downloading and installation instructions [here](https://gcc.gnu.org/install/).
+3. Download the repo and include the submodules using the following commands.
+    - `git clone --recurse-submodules git@github.com:FreeRTOS/FreeRTOS-Cellular-Interface.git ./FreeRTOS-Cellular-Interface`
+    - `cd ./FreeRTOS-Cellular-Interface`
+    - `git submodule update --checkout --init --recursive`
+
+### To build and run coverity:
+Go to the root directory of the library and run the following commands in terminal:
+1. Update the compiler configuration in Coverity
+  ~~~
+  cov-configure --force --compiler cc --comptype gcc
+  ~~~
+2. Create the build files using CMake in a `build` directory
+  ~~~
+  cmake -B build -S test
+  ~~~
+3. Go to the build directory and copy the coverity configuration file
+  ~~~
+  cd build/
+  ~~~
+4. Build the static analysis target
+  ~~~
+  cov-build --emit-complementary-info --dir cov-out make coverity_analysis
+  ~~~
+5. Go to the Coverity output directory (`cov-out`) and begin Coverity static analysis
+  ~~~
+  cd cov-out/
+  cov-analyze --dir . --coding-standard-config ../../tools/coverity/misra.config --tu-pattern "file('.*/source/.*')"
+  ~~~
+6. Format the errors in HTML format so that it is more readable while removing the test and build directory from the report
+  ~~~
+  cov-format-errors --dir . --file "source" --exclude-files '(/build/|/test/)' --html-output html-out;
+  ~~~
+7. Format the errors in JSON format to perform a jq query to get a simplified list of any exceptions.
+  NOTE: A blank output means there are no defects that aren't being suppressed by the config or inline comments.
+  ~~~
+  cov-format-errors --dir . --file "source" --exclude-files '(/build/|/test/)' --json-output-v2 defects.json;
+  echo -e "\n-------------------------Non-Suppresed Deviations, if any, Listed Below-------------------------\n";
+  jq '.issues[] | .events[] | .eventTag ' defects.json | sort | uniq -c | sort -nr;
+   echo -e "\n-------------------------Non-Suppresed Deviations, if any, Listed Above-------------------------\n";
+  ~~~
+
+For your convenience the commands above are below to be copy/pasted into a UNIX command friendly terminal.
+ ~~~
+ cov-configure --force --compiler cc --comptype gcc;
+ cmake -B build -S test;
+ cd build/;
+ cov-build --emit-complementary-info --dir cov-out make coverity_analysis;
+ cd cov-out/
+ cov-analyze --dir . --coding-standard-config ../../tools/coverity/misra.config --tu-pattern "file('.*/source/.*')";
+ cov-format-errors --dir . --file "source" --exclude-files '(/build/|/test/)' --html-output html-out;
+ cov-format-errors --dir . --file "source" --exclude-files '(/build/|/test/)' --json-output-v2 defects.json;
+ echo -e "\n-------------------------Non-Suppresed Deviations, if any, Listed Below-------------------------\n";
+ jq '.issues[] | .events[] | .eventTag ' defects.json | sort | uniq -c | sort -nr;
+ echo -e "\n-------------------------Non-Suppresed Deviations, if any, Listed Above-------------------------\n";
+ cd ../../;
+ ~~~
+
+You should now have the HTML formatted violations list in a directory named `build/cov-out/html-output`.
+With the current configuration and the provided project, you should not see any deviations.
