    <p>Looks like your controller does too much work. Try to abstract the json reader in another class, and inject it in the controller. That way you will have 2 independent tests - one for the reader itself, and another one for the controller, that it just calls the reader, w/o actually having to think abouit how the reader works.</p> <p>Something like this (pseudo code):</p> <pre><code>public interface IJsonReader { dynamic SqueezeJson(Stream stream); } public class JsonReader : IJsonReader { //implement SqeezeJson method } public class MyController { private readonly IJsonReader _jsonReader; public MyController(IJsonReader jsonReader) { _jsonReader = jsonReader; } public ActionResult Create() { var data = _jsonReader.SqeezeJson(Context.Request.InputStream); //... do wahtever needed } } // ... and the tests [Test] public void SqueezeJsonTest() { //test that the reader works as expected } public void ControllerTest() { //arrange var requestStream = Mock.Of&lt;Stream&gt;(); var request = Mock.Of&lt;HttpRequestBase&gt;( r =&gt; r.InputStream == requestStream &amp;&amp; r.Url == "http://whatever"); var context = Mock.Of&lt;HttpRequestBase&gt;(c=&gt;c.Request == request); dynamic sqeezedData = new ExpandoObject(); // populate with the expected data from reader var mockReader = new Mock&lt;IJsonReader&gt;(); mockReader.Setup(r=&gt;r.SqeezeJson(requestStream)).Returns(sqeezedData); var controller = new MyController(); controller.Context = context; //act var result = controller.Create(); //assert //whatever is needed to verify that the controller processed the sueezed data } </code></pre>

    1. COthanks for the answer. Unfortunately, I'm not at liberty to refactor. Also, this doesn't help with the specific error I mentioned.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
