WeChat Mini Program Automation Testing

CRITICAL: Batch Execution Rule

ALWAYS write a single Python script that uses WeappTestRunner to batch ALL operations, then execute it with ONE python call.

Each tool call costs ~30-60s overhead. A test with 10 individual CLI calls takes 5-15 minutes; the same 10 operations batched into one script take ~5 seconds.

Execution pattern

Plan all operations the user needs
Write a single Python script using WeappTestRunner
Run with one python command
Read output and report results

Example

import sys
sys.path.insert(0, r"path_to_weapp-automation_skill\scripts")
from weapp_automation import AutomationConfig, WeappTestRunner

config = AutomationConfig(
    project_path=r"path_to_your_miniapp\my_mini_app",
    ws_endpoint="ws://localhost:9420"
)

runner = WeappTestRunner(config)
results = (runner
    .navigate("pages/index/index")
    .wait(2)
    .screenshot("home.png")
    .click(".category-item")
    .wait(1)
    .screenshot("after_click.png")
    .get_results())

print(runner.get_summary())
for r in results:
    print(r)

Save as a .py file and run with python script.py.
