What a VS Code verified publisher badge means, compared with Open VSX →
Run and debug JUnit or TestNG test cases.
Daily readings on both stores, taken by us. As of 24 Sept 2026.
Each bar is one day’s change in the store’s own counter. Open VSX counts a download on every update, so a day includes updates by people who already had it. Days before 5 Sept are reconstructed from public archives rather than read by us.
Positions observed daily on both stores. Neither store publishes this, and the two run separate search engines over separate catalogues.
#6 on Marketplace for “java”, #89 on Open VSX.
