This should resolve your clang-format violation. (moving `UnsafeBufferUsageTest.h` below the `UnsafeBufferUsageExtractor.h` include)

```suggestion
#include "TestFixture.h"
#include "clang/AST/DynamicRecursiveASTVisitor.h"
#include "clang/Frontend/ASTUnit.h"
#include "clang/ScalableStaticAnalysisFramework/Analyses/UnsafeBufferUsage/UnsafeBufferUsageExtractor.h"
