how to take picture only when a jest test failed?

[adamchenwei]

I researched this topic and saw a similar question in https://github.com/allure-framework/allure-jasmine/issues/10 and
But I wonder if this is something jest do or allure, or... jest-allure?
Is there some sort of each test on error event can be utilized in each description / it scope when onError without building another custom reporter?
I know I can take a screenshot by building another reporter (https://stackoverflow.com/questions/48388206/how-to-run-function-when-any-test-fails-jest)... but is that the only way to go in this case?

Thanks!

i'm using puppeeteer,
i use to try / catch every puppeteer method in a helper library and then i add a screenshot in the catch

for example

        try {
            const selectorScreenshot = await selectorImage.screenshot()
            await expect(selectorScreenshot).toMatchImageSnapshot({
                failureThreshold: 0,
                failureThresholdType: "percent",
                diffDirection: "vertical"
            })
        } catch (error) {
            const selectorScreenshot = await selectorImage.screenshot()
            reporter.addAttachment("imageShouldToBe", selectorScreenshot, "image/png");
            throw new Error(`unable to take screenshot ` + error)
        }
