Static code analysis tools for Salesforce

static-code-analysis-

Today, development has to be agile as developers are under pressure to deliver timely releases while meeting quality and compliance standards. Coding is an effort-intensive task, be it on Salesforce or any other platform. Complex, legacy environments come with the possibility of having code quality issues, increasing development teams’ efforts in implementing new projects, problem-free.

How can you ensure development agility and release security in your development pipeline and processes? Salesforce applications can perform better if code execution is efficient and CI/CD pipelines have automated release management. However getting back to basics, optimizing code and execution comes down to static code analysis tools.

What is static code analysis?

Static code analysis is a method of utilizing technology for debugging code by examining and identifying vulnerabilities before running a program. It identifies code issues and errors, checks standardization violations, and presents security weaknesses in the code. Static code analysis can be done manually or by using automated tools. Manual code analysis is a time-consuming process, especially in more complex organizations, and does not have a 100% guarantee of revealing vulnerabilities, whereas automated static code analysis tools are proven to save on effort, time, and ROI.

How does a static code analysis tool work?

In an automated review process, static code analysis tools work in the following way:

  • Static code analysis tool syncs to the coding environment.
  • Developers write code.
  • Static code analysis tool checks for code bugs and vulnerabilities.
  • An analysis report or alert is created.
  • Developers fix the critical issues.

Ensuring Code Quality and Security

Static code analysis is crucial to identifying weaknesses in source code and code quality. These gaps might lead to vulnerabilities in the application, which can compromise application quality and functionality once deployed. In addition to maintaining quality, adherence to coding guidelines and standards can be enhanced with static code analysis tools. It will help organizations implement code quality guidelines easily across their environments while also providing more project transparency.

Static Analysis vs. Dynamic Analysis

Static analysis and dynamic analysis fundamentally have the same goals – to detect defects. However, the difference between the two is the software development lifecycle stage to which the analysis is applied.

In static analysis, defects are detected before executing the code. The code is analyzed against a given set of rules or coding standards. Static code analysis is set before the unit or integration testing. Organizations using DevOps and CI/CD pipelines have static analysis as a quality check parameter before pushing the code from the testing environment to production.

In dynamic analysis, defects are detected after you run a program. There are no set of rules as the source code may run with a variety of inputs. Dynamic analysis can be used to troubleshoot production incidents faster. In CI/CD pipelines, it will prevent bad quality code from going into production.

Not all coding errors are discovered in dynamic testing, but they can be found in static testing. Static code analysis tools provide more comprehensive coverage of code quality through the development pipeline.

What are the benefits of static code analysis tools?

Below is a breakdown of the benefits you gain by applying static code analysis tools to your DevOps workflow:

  • Code Optimization: Static analysis tools provide early insights into code errors and issues. This enables early vulnerability identification and fixes before the testing stage. It helps in reducing efforts, costs, and complexities that would occur if defects were discovered at a later stage in the software development lifecycle.
  • Speed: Manual code review is time-consuming. Using static code analysis tools, large volumes of code can be analyzed quickly, thereby increasing productivity and reducing resource efforts.
  • Depth: Static code analysis tools analyze code in-depth and find weaknesses in the exact locations in the codebase. Good static code analysis tools will pinpoint the error with a single click.
  • Accuracy: Static analysis tools accurately point out vulnerabilities and adherence to common coding standards. Common errors committed by developers are easily identified.
  • Security: In complex coding environments, developers can miss security vulnerabilities in a manual review. The usage of static analysis tools helps in improving the security aspect of the application. These tools can identify issues like XSS in lightning applications, prevent SOQL/SOSL injections, cross-site scripting, etc.

Code review in Salesforce

With dedicated Salesforce DevOps teams in charge of code review, why does static code analysis matter? Maintaining code quality helps with the longevity of Salesforce applications in design, implementation, and updates. Static code review tools assist teams in identifying common errors, increase testing turnaround time, and increase efficiency and productivity with lower margin of error. The ways that static code analysis tools benefit Salesforce development are:

  • Prevent bad coding
  • Enforce organization coding standards
  • Prevent security vulnerabilities
  • Identify performance gaps
  • Identify weakness in testing
  • Identify and eliminate bad code
  • Reduce code duplication

Static code analysis tools compatible with Salesforce are important in order to work with Salesforce coding languages, like Apex, Lightning, Visualforce, and Metadata.

Salesforce Apex static code analysis tools

Apex is a development platform for building SaaS applications and the proprietary language for the Lightning platform. It lets developers access Salesforce’s back-end database and client-server interfaces to create third-party SaaS applications. Apex API can be used to access user data on Salesforce. You can choose from multiple static code analysis tools for Apex Salesforce. PMD is a free tool while the others like Checkmarx and CodeScan will require paid licenses to detect cross-site scripting, SOQL injections, SOSL injections, frame spoofing, and access control issues. Free tools have technical limitations to the lines scanned, the rules, and access to the platform.

Salesforce Lightning code analysis tools

Salesforce Lightning is a component-based framework for app development that helps simplify business processes. Lightning Web Components (LWC), an updated version of Lightning components, implements lightweight frameworks built on web standards, giving Salesforce Admins and Developers the tools to enhance user experience. There are a limited number of code analysis tools for Salesforce Lightning in the market. There is a Lightning CLI component in CodeScan, which is built to catch the OWASP top vulnerabilities. On Salesforce, CodeScan can identify specific security flaws like FLS violations, SOQL-injections, CRUD, and more. CodeScan has also over 350+ security and quality rules and is one of the ideal choices for Lightning. It integrates directly with Salesforce and popular CI/CD pipelines.

Visualforce code analysis tools

Visualforce is a component-based user interface(UI) framework that developers use to create dynamic, reusable interfaces. It is part of Salesforce’s Force platform as a service and is supported by many static code analysis tools. Apex PMD or PMD (Programming Mistake Detector) has a few built-in rules for Visualforce pages. Other products with static code analysis tools that support the Visualforce interface include Checkmarx, SonarQube, and CodeScan.

Static code analysis tools for Salesforce Metadata

Metadata in salesforce is about the fields, code, logic, configurations, and page layouts that enable the architecture of Salesforce information, platform, and environment. You can import Metadata and also modify it through the Salesforce Metadata API. CodeScan static code analysis tool has Metadata scanning along with numerous security and quality rules. Salesforce has a variety of low code and pro-code development options as well. While static code analysis tools are necessary for both low-code and pro-code development, the urgency for a tool may be lower for low-code options. In any event, it is important that the static analysis tools support the ability to scan Metadata.
