junit參數化測試可以處理多少個最大參數？

我存儲在Iterable<Object[]>總2799030參數和我期待junit建立/啓動這些許多測試。但它只是掛在Iterable<Object[]>加載所有參數之後 - 參見下面的屏幕截圖：junit參數化測試可以處理多少個最大參數？

它正常工作與少量的參數（5000-10000）。我也試圖與更高的JVM運行內存（-Xms1024M -Xmx4096M）

更新：我也試着從CLI而不是IDE運行，從錯誤下面好像我應該有更多的內存運行或更改我的設計以小批量運行。 - 想法？

更改設計執行測試

例如：

使你的類測試10種方法。
每種方法運行10000個項目。
並行測試運行。
消耗時發現或執行物品。

，如果你不是不能做到這一點。您需要更多內存才能進行測試，
