This was released at the end of 2014 and has not been updated since. Instead, development work has moved to <tt>xmlunit</tt> 2.x, which is up to around 2.5.1 at the time of writing.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">I don't see any likelihood that version 1.6 will ever be updated for compatibility or extended in any way. As version 2.5.1 is already a dependency of Spring 5's test module, it seems a given that we need to move onto the new release at some point, and doing this sooner rather than later is probably advisable.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">The 2.x version has new APIs native to it, but it also comes with a "legacy" module that implements the old API with some deviations. So there's probably a relatively low-effort path for migration although they do warn that the legacy API won't get any new features.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">One thing that does look as if it may affect us when using the "legacy" API is that all static configuration has been removed. For example, one could previously say <tt>XMLUnit.setIgnoreWhitespace()</tt> to cause all tests to ignore whitespace. We do this in some of our test parent classes.</p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">This seems like a good change to the API (tests should be independent, surely) but there's a possibility that some of our tests will now fail in an environment where this default cannot be set. Such tests would need to have relevant input documents wrapped in a <tt>WhitespaceStrippedSource</tt> or use a <tt>DiffBuilder</tt> with the <tt>ignoreWhitespace</tt> property set, as described in <a href="https://github.com/xmlunit/user-guide/wiki/Migrating-from-XMLUnit-1.x-to-2.x" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">https://github.com/xmlunit/user-guide/wiki/Migrating-from-XMLUnit-1.x-to-2.x</a></p> <p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">I will do some nature study on all this, starting from the V8 parent project (where I need Spring 5 anyway) but I will also try to investigate whether we can move the V7 parent forward without too much work.</p> </td>
