How can you create a new (xml) file in angular testing

Question

I am working on an unittest in a Angular(2) project. But I ran into an issue that I can not create a new File for my test.

In my test I have the following code:

const newfile = new Blob(['ANEWFILE001'], {
    type: 'application/xml',
    endings: 'native'
});

data = [
    {
        file: {
            file: new File(newfile, "FILENAME001.xml",)
        } as FileLoadBar
    }
];

file: new File(newfile, "FILENAME001.xml",)
newfile results in the following error:

Argument of type 'Blob' is not assignable to parameter of type '(string | ArrayBuffer | Blob | ArrayBufferView)[]'.
Property 'find' is missing in type 'Blob'.

How do I create a new File in an angular unitetest.
If there is any information needed for solving this issue please let me know.

Adding parenthesis is not the solution (blob has no compatible call signature error will occur) — Babulaas

I missed the brackets.

file: new File([newfile], "FILENAME001.xml",)
