hierarchy

I'm used to JUnit, in JUnit it is possible to group several tests (usually related to a class) just by defining these tests in a single file (class) and annotating them with @Test . Then, to run several of these tests, a TestSuite is created with @Suite.SuiteClasses and so on. In specs2 it is possible to group several tests at two different levels extending some Specification . For example: "Whatever" should { "do its job when possible" in { whatever(new Thing).work must beSome } "return none when not possible" in { whatever(null).work must beNone } } We can group several Specification of this

Is it possible to assign a fixed value to a property on a child instance when building a parent with Autofixture? It will add default values to all the properties on the child instance like a charm, but I would like to override and assign a specific value to one of the properties on the child instance. Given this parent/child relationship: public class Person { public string FirstName { get; set; } public string LastName { get; set; } public Address Address { get; set; } } public class Address { public string Street { get; set; } public int Number { get; set; } public string City { get; set; }

The MySQL databse stores tree with the help of materialized path data structure. How to select all parents of the given node? I use dot '.' as path separator, and database structure includes 'level' field that indicates the depth of a node in the tree. Lets I have those tree and need all parents of the node 'a.b.d.e': id | path a | a b | a.b c | a.b.c d | a.b.d e | a.b.d.e f | a.f The script should return: a a.b a.b.d a.d.d.e (optional) How to do that in MySQL? Ivan Z I've found the solution in the question posted by @quambo . Here it is: SELECT * FROM table WHERE ? LIKE id||% ORDER BY path

How do you build a hierarchical set of tags with data in PHP? For example, a nested list: <div> <ul> <li>foo </li> <li>bar <ul> <li>sub-bar </li> </ul> </li> </ul> </div> This would be build from flat data like this: nested_array = array(); nested_array[0] = array('name' => 'foo', 'depth' => 0) nested_array[1] = array('name' => 'bar', 'depth' => 0) nested_array[2] = array('name' => 'sub-bar', 'depth' => 1) It would be nice if it were nicely formatted like the example, too. Edit: Added formatting As already said in the comments, your data structure is somewhat strange. Instead of using text

How can I query this parent-child hierarchy to produce a result set in which the levels are in their own columns? Sample data: SET NOCOUNT ON; USE Tempdb; IF OBJECT_ID('dbo.Employees', 'U') IS NOT NULL DROP TABLE dbo.Employees; CREATE TABLE dbo.Employees ( empid INT NOT NULL PRIMARY KEY, mgrid INT NULL REFERENCES dbo.Employees, empname VARCHAR(25) NOT NULL, salary MONEY NOT NULL, CHECK (empid <> mgrid), CHECK (empid > 0) ); CREATE UNIQUE INDEX idx_unc_mgrid_empid ON dbo.Employees(mgrid, empid); INSERT INTO dbo.Employees(empid, mgrid, empname, salary) VALUES (1, NULL, 'David' , $10000.00), (2,
