You can use string literals to test for format (`) instead of creating lines and joining them.

Yes, I prefer creating lines since I find it easier to keep track of the exact spacing on each line.

You can see in the demo (and these tests) that the new plot yaml still doesn't line up perfectly with the previous plots since we're grabbing the indent level from a nested item (x: recall in this example) which doesn't always tell you the plots actual indent level.

Since I'm not seeing an simple way to make sure it's all aligned correctly, I chose to aim for just ensuring that the new yaml is valid and doesn't break anything :)

' x: epochs',
' y:',
' data.json: accuracy',
''
].join('\n')
mockedReadFileSync.mockReturnValueOnce(mockDvcYamlContent)
mockedReadFileSync.mockReturnValueOnce(mockDvcYamlContent)

addPlotToDvcYamlFile('/', {
template: 'simple',
title: 'simple_plot',
x: { 'data.json': ['epochs'] },
y: { 'data.json': ['accuracy'] }
})

expect(mockedOpenTextDocument).toHaveBeenCalledTimes(1)
expect(mockedWriteFileSync).toHaveBeenCalledWith(
'//dvc.yaml',
mockDvcYamlContent + mockPlotYamlContent
)
})
})

We check for if the lines have a list item with no indentation and trim our new plot lines to ensure that the new plot also has 0 indentation for its list item.

line.startsWith(' ') ? line.slice(spaces) : line
)
: newPlotLines
}
