  Static analyzers are tool sets which are proving to be indispensable to
modern programmers. These enable the programmers to detect possible errors and
security defects present in the current code base within the implementation
phase of the development cycle, rather than relying on a standalone testing
phase. Static analyzers typically highlight possible defects within the
'static' source code and thus does not require the source code to be compiled
or executed. The Scala programming language has been gaining wider adoption
across various industries in recent years. With such a wide adoption of tools
of this nature, this paper presents an overview on the static analysis tools
available, both commercial and open-source, for the Scala programming language.
This paper discusses in detail about the types of defects that each of these
tools can detect, limitations of these tools and also provide potential
research direction that can improve the current state of static analyzers for
the Scala programming language.
