Frasy

Frasy is a Windows desktop application for automated PCBA (Printed Circuit Board Assembly) testing. It combines a C++ host process for UI, hardware communication, and test orchestration with a Lua scripting layer where all test logic lives — allowing test engineers to write and iterate on test sequences without recompiling the application.

Quick Example

Sequence("Power On", function()
    Test("Check Supply Voltage", function()
        local daq = Context.map.ibs.daq --[[@as DAQ]]
        local v = daq:MeasureVoltage(Context.values.route._24VDC) -- Reads the voltage on a testpoint
        Expect(v.average, "Supply Voltage"):ToBeInPercentage(24, 1.0) -- Asserts the value read
    end)
end)

Key Features

  • Descriptive test scripting — write what a board should do, not how to check it
  • Multi-UUT support — test multiple boards in parallel with built-in synchronization
  • CANopen hardware integration — communicate with instrumentation boards over SLCAN
  • Live UI panels — log viewer, result viewer, statistical analyzer, CANopen object dictionary browser
  • Hash-verified scripts — integrity checking on all Lua files before execution
  • Test report generation — export results in JSON, Markdown, Key-Value, or PDF format
