I Will keep migrating other files

@Freedisch Are tests working fine locally? I think you might haven't generated the snapshots.

Freedisch · 2023-08-15T09:51:46Z

@anshgoyalevil, I just noticed, I will update it with the shallow func u created, previously

Mirgation to RLT with QualityMetrics/BannerText.test.js
QualityMetrics/CountCard.test.js pass test

There is an expected behavior with snapshots with QualityMetrics/MetricCard.test.js and the shallow func does solve it. I will keep looking into that.

packages/jaeger-ui/src/components/QualityMetrics/CountCard.test.js


 import CountCard from './CountCard';
+import shallow from '../../utils/ReactShallowRenderer.test';


can the last two tests be modified to assert specific things on the output instead of using shallow? This seems like a simply component to test

Alright, I'm on it

Freedisch · 2023-08-15T23:06:46Z

@yurishkuro, I have updated both tests and currently, they no longer snapshots

yurishkuro · 2023-08-16T15:03:53Z

packages/jaeger-ui/src/components/QualityMetrics/CountCard.test.js

+    const { getByText } = render(<CountCard count={count} title={title} examples={examples} />);
+
+    const countElement = getByText('108');
+    const titleElement = getByText('Test Title');


simplify

Suggested change

const titleElement = getByText('Test Title');

expect(getByText(title)).toBeInTheDocument();

this makes the test easier to read

yurishkuro · 2023-08-16T15:46:34Z

@anshgoyalevil do you mind reviewing this?

anshgoyalevil · 2023-08-16T15:47:30Z

@yurishkuro Sure. Would be happy to review 🚀

anshgoyalevil · 2023-08-16T16:16:03Z

packages/jaeger-ui/src/components/QualityMetrics/BannerText.test.js

  });

  it('renders header when props.bannerText is a string', () => {
-    expect(shallow(<BannerText bannerText="foo text" />)).toMatchSnapshot();


Since toMatchSnapshot() is no longer used, the snapshots created for this test needs to be purged.
You can use the command yarn test --updateSnapshot for that.

anshgoyalevil · 2023-08-16T16:16:46Z

packages/jaeger-ui/src/components/QualityMetrics/BannerText.test.js

-          }}
-        />
-      )
-    ).toMatchSnapshot();


Snapshots need to be purged for this too. Otherwise, the tests would pass, but CI will fail.

anshgoyalevil · 2023-08-16T16:20:16Z

packages/jaeger-ui/src/components/QualityMetrics/BannerText.test.js

  });

  it('renders header when props.bannerText is a string', () => {
-    expect(shallow(<BannerText bannerText="foo text" />)).toMatchSnapshot();
+    const { getByText } = render(<BannerText bannerText="foo text" />);


You can use most of these functions using the screen object from @testing-library/react.
Example,

render(<BannerText bannerText="foo text" />); expect(screen.getByText('foo text')).toBeInTheDocument();

Same goes for other such usages as well

use the same constants, not literal strings
