feat: add integration tests for published SDKs v0.2.0
Add integration test scripts to verify published npm and PyPI packages work correctly. Both tests perform the same workflow: - Generate a test image with timestamp - Register the image with Numbers Protocol - Update headline metadata - Verify with search engine - Retrieve asset tree for provenance Tests verified both @numbersprotocol/capture-sdk@0.2.0 (npm) and numbersprotocol-capture-sdk==0.2.0 (PyPI) packages work correctly.

# Capture SDK Integration Tests
2+
3+
Integration tests for the published Capture SDK packages to verify they work correctly after release.
4+
5+
## Prerequisites
6+
7+
You need a valid Numbers Protocol Capture API token. Get one from:
8+
https://captureapp.xyz/
9+
10+
Set the token as an environment variable:
11+
```bash
12+
export CAPTURE_TOKEN=your_token_here
13+
```
14+
15+
## TypeScript Test
16+
17+
Tests the npm package `@numbersprotocol/capture-sdk@0.2.0`.
18+
19+
### Setup
20+
```bash
21+
cd integration-tests
22+
npm install
23+
```
24+
25+
### Run
26+
```bash
27+
npm run test:ts
28+
```
29+
30+
Or directly:
31+
```bash
32+
npx tsx test-published-sdk.ts
33+
```
34+
35+
## Python Test
36+
37+
Tests the PyPI package `numbersprotocol-capture-sdk==0.2.0`.
38+
39+
### Setup
40+
```bash
41+
cd integration-tests
42+
pip install -r requirements.txt
43+
```
44+
45+
### Run
46+
```bash
47+
python test_published_sdk.py
48+
```
49+
50+
Or using npm script:
51+
```bash
52+
npm run test:py
53+
```
54+
55+
## What the Tests Do
56+
57+
Both tests perform the same workflow:
58+
59+
1. **Generate Test Image** - Creates a PNG image with the current timestamp
60+
2. **Register Image** - Uploads and registers the image with Numbers Protocol
61+
3. **Update Metadata** - Updates the asset's headline metadata
62+
4. **Verify Engine Search** - Searches for the asset using the verify engine
63+
5. **Get Asset Tree** - Retrieves the provenance data for the asset
64+
65+
## Expected Output
66+
67+
```

[OK] Integration test completed successfully
108+
```
109+
110+
## Troubleshooting
111+
112+
### "CAPTURE_TOKEN environment variable is required"
113+
Make sure you've set the environment variable:
114+
```bash
115+
export CAPTURE_TOKEN=your_token_here
116+
```
117+
118+
### "Asset not yet indexed"
119+
This is expected for newly registered assets. The verify engine takes some time to index new assets.
120+
121+
### Network errors
122+
Check your internet connection and that the Numbers Protocol API is accessible.
