A Visual Studio Code extension that draws a visual flow of TestNG-style Java tests: which @Test methods run in what order, how they depend on each other, and where parameters and inherited steps come from—without reading hundreds of lines by hand.
What it does
Reads .java sources in your workspace and builds a directed graph from @Test and dependsOnMethods.
Layers methods by dependency depth so you can spot parallel groups (tests with no ordering between them in the same layer).
Follows extends to pull in superclass @Test methods and shows the declaring class for each step.
Lets you click a step to open the file and highlight the method declaration line.
Inspired by a “flow preview” workflow (similar in spirit to FlowRunner-style UIs): one place to see the scenario at a glance.

Who it’s for
Teams using TestNG with dependsOnMethods chains in Java flow/scenario classes (e.g. API E2E flows). It is a heuristic viewer, not a full Java compiler—see documentation.md for limits.
Quick start
Install the extension (from a packaged .vsix or by running from source—see below).
Open your Java project in VS Code.
Open the Auto Flow activity bar and the TestNG Flow Preview view, or run Auto Flow View: Open TestNG Flow Diagram and pick a .java file or folder.
Use the dropdown if you analyzed multiple files; click a card to jump to code.
Use Search… to filter cards by method name substring, All classes to narrow by declaring class, and Refresh after you edit sources on disk.
Installation
Download the vsix file from releases folder (recommended to download latest version)
Drag and drop this vsix file into extension sidebar
Restart extensions
