Cannot read property getBlock of undefined

Question

I am facing issues with truffle test. When I run truffle test, I am getting the following error:

TypeError: Cannot read property ' getBlock ' of undefined.

But it runs fine on console.

getBlock is used by web3 and to use it, you have to mention the web3 provider in your code. Like this:

if (typeof web3 !== 'undefined') {
    // Use Mist/MetaMask's provider
    web3 = new Web3(web3.currentProvider);
