Add tests for the new /items POST handlers to the DSpace 6.x branch of my dspace-statistics-api
It took a bit of extra work because I had to learn how to mock the responses for when Solr is not available
Tag and release version 1.3.0 on GitHub: https://github.com/ilri/dspace-statistics-api/releases/tag/v1.3.0
Trying to test the changes Atmire sent last week but I had to re-create my local database from a recent CGSpace dump
During the FlywayDB migration I got an error:

<li>I checked the database migrations with <code>dspace database info</code> and they were all OK
<ul>
<li>Then I restarted the Tomcat again and it started up OK…</li>
</ul>
</li>
<li>There were two issues I had reported to Atmire last month:
<ul>
<li>Importing items from the command line throws a <code>NullPointerException</code> from <code>com.atmire.dspace.cua.CUASolrLoggerServiceImpl</code> for every item, but the item still gets imported</li>
<li>No results for author name in Listing and Reports, despite there being hits in Discovery search</li>
</ul>
</li>
<li>To test the first one I imported a very simple CSV file with one item with minimal data
<ul>
<li>There is a new error now (but the item does get imported):</li>
</ul>
</li>
</ul>

</code></pre><ul>
<li>Solr returns <code>hits=18</code> for the L&R query, but there are no result shown in the L&R UI</li>
<li>I sent all this feedback to Atmire…</li>
</ul>
<h2 id="2020-10-07">2020-10-07</h2>
<ul>
<li>Udana from IWMI had asked about stats discrepencies from reports they had generated in previous months or years
<ul>
<li>I told him that we very often purge bots and the number of stats can change drastically</li>
<li>Also, I told him that it is not possible to compare stats from previous exports and that the stats should be taking with a grain of salt</li>
</ul>
</li>
<li>Testing POSTing items to the DSpace 6 REST API
<ul>
<li>We need to authenticate to get a JSESSIONID cookie first:</li>
</ul>
</li>
</ul>
<pre><code>$ http -f POST https://dspacetest.cgiar.org/rest/login email=aorth@fuuu.com 'password=fuuuu'
$ http https://dspacetest.cgiar.org/rest/status Cookie:JSESSIONID=EABAC9EFF942028AA52DFDA16DBCAFDE
</code></pre><ul>
<li>Then we post an item in JSON format to <code>/rest/collections/{uuid}/items</code>:</li>
</ul>
<pre><code>$ http POST https://dspacetest.cgiar.org/rest/collections/f10ad667-2746-4705-8b16-4439abe61d22/items Cookie:JSESSIONID=EABAC9EFF942028AA52DFDA16DBCAFDE < item-object.json
</code></pre><ul>
<li>Format of JSON is:</li>
</ul>
<pre><code>{ "metadata": [
{
"key": "dc.title",
"value": "Testing REST API post",
"language": "en_US"
},
{
"key": "dc.contributor.author",
"value": "Orth, Alan",
"language": "en_US"
},
{
"key": "dc.date.issued",
"value": "2020-09-01",
"language": "en_US"
}
],
"archived":"false",
"withdrawn":"false"
}
</code></pre><ul>
<li>What is unclear to me is the <code>archived</code> parameter, it seems to do nothing… perhaps it is only used for the <code>/items</code> endpoint when printing information about an item
<ul>
<li>If I submit to a collection that has a workflow, even as a super admin and with “archived=false” in the JSON, the item enters the workflow (“Awaiting editor’s attention”)</li>
<li>If I submit to a new collection without a workflow the item gets archived immediately</li>
<li>I created <a href="https://gist.github.com/alanorth/40fc3092aefd78f978cca00e8abeeb7a">some notes</a> to share with Salem and Leroy for future reference when we start discussion POSTing items to the REST API</li>
</ul>
</li>
<li>I created an account for Salem on DSpace Test and added it to the submitters group of an ICARDA collection with no other workflow steps so we can see what happens
<ul>
<li>We are curious to see if he gets a UUID when posting from MEL</li>
</ul>
</li>
<li>I did some tests by adding his account to certain workflow steps and trying to POST the item</li>
<li>Member of collection “Submitters” step:
<ul>
<li>HTTP Status 401 – Unauthorized</li>
<li>The request has not been applied because it lacks valid authentication credentials for the target resource.</li>
</ul>
</li>
<li>Member of collection “Accept/Reject” step:
<ul>
<li>Same error…</li>
</ul>
</li>
<li>Member of collection “Accept/Reject/Edit Metadata” step:
<ul>
<li>Same error…</li>
</ul>
</li>
<li>Member of collection Administrators with no other workflow steps…:
<ul>
<li>Posts straight to archive</li>
</ul>
</li>
<li>Member of collection Administrators with empty “Accept/Reject/Edit Metadata” step:
<ul>
<li>Posts straight to archive</li>
</ul>
</li>
<li>Member of collection Administrators with populated “Accept/Reject/Edit Metadata” step:
<ul>
<li>Does <em>not</em> post straight to archive, goes to workflow</li>
</ul>
</li>
<li>Note that community administrators have no role in item submission other than being able to create/manage collection groups</li>
</ul>
<h2 id="2020-10-08">2020-10-08</h2>
<ul>
<li>I did some testing of the DSpace 5 REST API because Salem and I were curious
<ul>
<li>The authentication is a little different (uses a serialized JSON object instead of a form and the token is an HTTP header instead of a cookie):</li>
</ul>
</li>
</ul>
<pre><code>$ http POST http://localhost:8080/rest/login email=aorth@fuuu.com 'password=ddddd'
$ http http://localhost:8080/rest/status rest-dspace-token:d846f138-75d3-47ba-9180-b88789a28099
$ http POST http://localhost:8080/rest/collections/1549/items rest-dspace-token:d846f138-75d3-47ba-9180-b88789a28099 < item-object.json
</code></pre><ul>
<li>The item submission works exactly the same as in DSpace 6:</li>
</ul>
<ol>
<li>The submitting user must be a collection admin</li>
<li>If the collection has a workflow the item will enter it and the API returns an item ID</li>
<li>If the collection does not have a workflow then the item is committed to the archive and you get a Handle</li>
