Procedures
Define your test sequence for your Units Under Test.
Overview
The Procedures allow you to set up the test sequence for one or more units under test. It provides analytics and test performances across multiple runs, including average test duration, yields, Cpk, and Control Chart for numerical values.
Integration
You can create a new procedure automatically from your test scripts by setting its ID, name, Unit Under Test, and test status.
Basic parameters
import openhtf as htf
from tofupilot.openhtf import TofuPilot
def main():
test = htf.Test(
procedure_id="FVT1",
procedure_name="PCB Testing", # By default set as "openhtf_test"
part_number="PCB1",
)
with TofuPilot(test):
test.execute(lambda: "PCB1A001") # Duration calculated during execution
if __name__ == '__main__':
main()
- Name
procedure_id
- Type
- str
- Description
Define unique procedure ID.
- Name
procedure_name
- Type
- str (optional)
- Description
Set or rename the procedure name.
- Name
run_passed
- Type
- bool
- Description
Set Pass/Fail status of the procedure.
- Name
duration
- Type
- timedelta (optional)
- Description
Determine duration of the test.
If a procedure has steps
but the procedure duration is not defined, the duration
will be automatically calculated as the sum of the durations of its steps
Advanced parameters
You can define several important additional parameters for your procedures, each covered in a separate section:
- Define Unit under test (UUT), which includes serial number, batch, revision, and part number.
- Break down test Steps
- Add Sub-units during assembly
- Include file Attachments
- Create customizable Reports
In-app view
In TofuPilot, you can explore different procedures in the Procedures tab. On a Procedure page (for example, procedure_id
FVT1 with the procedure_name
PCB Testing), you can navigate between various tabs that display analytics for all runs executed from this procedure. These include:
- The status of Runs over time, defined by
run_passed
- The average test Duration over time, compute from
duration
- First-Pass Yield
- Cpk for tests with numerical measurements and limits.
These features will be explained in more detail in the Test steps analysis section.
