NUnitAssertGen
Generates NUnit Assert.That statement strings from live object instances using reflection.
Paste the output directly into your test methods — no more hand-writing assertions for complex objects.
Installation
dotnet add package NUnitAssertGen
Quick start
using NUnitAssertGen;
var result = myService.GetPerson(42);
Console.WriteLine(AssertGenerator.Generate(result, "result"));
Example output:
Assert.That(result.Name, Is.EqualTo("Alice"));
Assert.That(result.Age, Is.EqualTo(30));
Assert.That(result.Tags, Is.EquivalentTo(new HashSet<string> { "admin", "user" }));
Assert.That(result.Scores, Has.Count.EqualTo(2));
Assert.That(result.Scores.ContainsKey("math"), Is.True);
Assert.That(result.Scores["math"], Is.EquivalentTo(new HashSet<int> { 95, 87 }));
Assert.That(result.Address.Street, Is.EqualTo("123 Main St"));
Assert.That(result.Address.ZipCode, Is.EqualTo(90210));
API
// Default options
string code = AssertGenerator.Generate(instance, "result");
// Quick depth override
string code = AssertGenerator.Generate(instance, "result", maxDepth: 3);
// Full control
string code = AssertGenerator.Generate(instance, "result", new GeneratorOptions { ... });
GeneratorOptions
| Property | Type | Default | Description |
|---|---|---|---|
MaxDepth |
int |
5 |
Maximum recursion depth into nested objects. A comment is emitted when the limit is hit. |
IncludePrivateProperties |
bool |
false |
Also reflect non-public instance properties. |
IncludeFields |
bool |
false |
Include public instance fields alongside properties. |
PropertyFilter |
Func<PropertyInfo, bool>? |
null |
Predicate to exclude properties by name, type, or attribute. |
FieldFilter |
Func<FieldInfo, bool>? |
null |
Predicate to exclude fields. Only applies when IncludeFields is true. |
EmitCountAssertions |
bool |
true |
Emit Has.Count.EqualTo(n) before per-element assertions on non-empty collections. |
MaxCollectionItems |
int |
int.MaxValue |
Cap on inline collection items; excess items produce a truncation comment. |
SortDictionaryKeys |
bool |
false |
Emit dictionary entries in ascending key order for deterministic output. |
NullHandling |
NullHandling |
AssertIsNull |
AssertIsNull, AssertNotNull, or Skip. |
UnreadablePropertyBehavior |
UnreadablePropertyBehavior |
Comment |
Comment, Skip, or Throw when a property getter throws. |
FloatTolerance |
double? |
null |
Emit .Within(tolerance) on float/double assertions instead of exact equality. |
DateTimeFormat |
DateTimeFormat |
Parse |
Parse (DateTime.Parse("…")), Ticks (new DateTime(ticks, kind)), or Constructor (new DateTime(y,m,d,…)). |
EnumFormat |
EnumFormat |
FullyQualifiedName |
FullyQualifiedName, ShortName, or NumericCast. |
FallbackFormatter |
Func<object, string?>? |
null |
Custom formatter for types the generator does not recognise. Return null to fall back to ToString(). |
GroupPropertiesByObject |
bool |
false |
Insert a blank line between assertion groups for each nested object. |
Supported types
| Type | Generated assertion |
|---|---|
Primitives (int, string, bool, Guid, DateTime, decimal, …) |
Is.EqualTo(…) |
HashSet<T> / ISet<T> |
Is.EquivalentTo(new HashSet<T> { … }) |
Dictionary<K, V> |
Has.Count + ContainsKey + value per entry |
Dictionary<K, HashSet<V>> |
Above, with nested Is.EquivalentTo(…) |
List<T> / T[] (primitive element) |
Is.EquivalentTo(new[] { … }) |
List<T> / T[] (complex element) |
Has.Count + per-index recursion |
| Nested objects | Recurses into public readable properties |
null |
Controlled by NullHandling option |
DateOnly / TimeOnly |
new DateOnly(…) / new TimeOnly(…) (.NET 6+) |
| Enums | Controlled by EnumFormat option |
