Single file report with history

[pulkomandy]

Describe the Bug

Hello,

We upgraded to the latest version of Allure and tried to enable the new single file report feature.

Unfortunately, while the report works fine, it doesn't generate the "history" directory. As a result, it's not possible to accumulate results from previous runs while using single file reports, unless we also generate a multi file one to get the history directory.

Did we miss something here? Is it possible to get history in single file reports?

Steps to Reproduce

1. Collect some test data
2. Generate single file report
3. Collect more test data
4. Generate new version of single file report
5. History from the previous report is not included

Expected Behaviour

Single file reports should still generate the history data (optionally) so that it's possible to generate single file reports with history.

Do you have any ideas on how this should be implemented, by chance? Do you expect Allure to generate a history folder together with index.html for the single file mode?

[pulkomandy]

I think that would work for us.

Another option would be to extract the history info from the single file index.html, but that seems more complex to do.

For now we will continue using multiple file reports. That's fine for us, but at least the documentation should mention this limitation then.

Is there any workaround to solve it temporarily?

[autokilla47]

any updates?

[baev]

The feature is already supported in Allure 3 https://github.com/allure-framework/allure3

As for today, there are no plans to support it in Allure 2, but at some point we may consider backporting it

@baev - can you give an example/point to documentation for how to accomplish this in allure3? I didn't see anything obvious in the README

[Valiantsin2021]

As a workaround - use separate commands to generate full report and then single html to replace the index.html with the standalone one

for Allure 3

To enable history, you need to specify historyPath configuration option. History data will be generated to the specified file regardless of generated report type.

import { defineConfig } from "allure";

export default defineConfig({
  name: "Allure Report Example",
  output: "./out/allure-report",
  historyPath: "./.allure/history.jsonl",
  plugins: {
    awesome: {
      options: {
        singleFile: true,
        reportLanguage: "en",
      },
    },
  },
});
