Test Data Generator
17 Nov 2011 | projects | comments | editI've pushed to github a new project, TestDataGenerator that should help with filling random objects with data. I felt the need for a tool like this when testing various serialization techniques and persistence strategies.
Basically this utility should construct the instance of an object using a public constructor, and fill all it's public, writable properties with random data.
Sample usage:
1 class Sample
2 {
3 private readonly int intValue;
4 private readonly string stringValue;
5
6 private Sample()
7 {
8 this.intValue = -1;
9 this.stringValue = null;
10 this.StringProp = null;
11 this.DateProp = DateTime.MinValue;
12 }
13
14 public Sample(int intVal, string stringVal)
15 :this()
16 {
17 this.intValue = intVal;
18 this.stringValue = stringVal;
19 }
20
21 public int PrivateInt { get { return intValue; } }
22 public string PrivateString { get { return stringValue; } }
23
24 public string StringProp { get; set; }
25 public DateTime DateProp { get; set; }
26 }
27
28 [Test]
29 public void Catalog_Can_Create_Using_Consutrctor()
30 {
31 Catalog catalog = new Catalog();
32 object instance = catalog.CreateInstance(typeof(Sample));
33
34 Assert.IsInstanceOfType(typeof(Sample), instance);
35 Sample sample = instance as Sample;
36
37 Assert.AreNotEqual(-1, sample.PrivateInt);
38 Assert.IsNotNull(sample.PrivateString);
39 Assert.IsNotNull(sample.StringProp);
40 Assert.AreNotEqual(DateTime.MinValue, sample.DateProp);
41 }For more samples see unit tests.
I'll try to add more cases ( abstract class, interface implementation discovery ) in the future. You are welcome to submit sample classes, preferably as unit tests.
