I'm attempt to stub the fs.writeFileSync method, but it's causing a
Reference Error.
In that case, oeverloading the fs method causes troubes as sinon.restore()
doesn't work.
*My stub.*
const writeImageStub = sinon.stub(fs, 'writeFileSync')
.callsFake((file, data, (err) => {
expect(file).to.be.a('string')
expect(getFileExtension(data)).to.equal('jpg')
expect(new Buffer.alloc(data)).to.be.a('object')
return '/static/images/image.jpg'
}))
*Reference error*: file is not defined.
How to do this, what causing this and exist other method?
*PS:*
Spying the method causes the write operation to be executed, on this case i
have to delete the files written, but how to get the filename as the format
is *filename.Date.now.extension*. Don't exist a way to store as a global
variable to do this.
