IAB Tech Lab VAST Tester

Tests IAB VAST ads. Contributed by the DoubleVerify team.

This tool is also hosted by IAB Tech Lab at vasttester.iabtechlab.com.

Getting Started

Install dependencies:

yarn

Get developing:

yarn start

Create a production build:

yarn run build

Architecture

This is a React app bootstrapped with Create React App. All state is maintained using Redux. Side effects of state mutation are modeled using redux-observable.

There are subdirectories for the standard React-Redux model:

• components/: React components (without Redux);
• containers/: React components connected to Redux's store;
• actions/: Redux action definitions;
• reducers/: Redux reducers;
• epics/: epics for redux-observable;
• middleware/: Redux middleware.

In addition to those, there are also:

• util/: various utility modules;
• style/: Sass style sheets for the app.

More detailed documentation will be added at a later stage. For now, we suggest exploring the source code.

Debugging

During development, you can use:

• React DevTools for React's DOM;
• Redux DevTools for Redux actions and redux-observable effects;
• Logger for Redux by setting localStorage.reduxLogger to true;

To Do

• OM SDK in-app support
• Resize support
• Canned test scenarios
• Reporting and recommendations
• VAST validation
