BlockHashTestCase

Tests that block rehashing works correctly.

Code

function testBlockRehash() {
  // No hook_block_info_alter(), no save.
  $this->doRehash();
  module_enable(array('block_test'), FALSE);
  // Save the new blocks, check that the new blocks exist by checking weight.
  _block_rehash();
  $this->assertWeight(0);
  // Now hook_block_info_alter() exists but no blocks are saved on a second
  // rehash.
  $this->doRehash();
  $this->assertWeight(0);
  // Now hook_block_info_alter() exists and is changing one block which
  // should be saved.
  $GLOBALS['conf']['block_test_info_alter'] = 1;
  $this->doRehash(TRUE);
  $this->assertWeight(10000);
  // Now hook_block_info_alter() exists but already changed the block's
  // weight before, so it should not be saved again.
  $this->doRehash();
  $this->assertWeight(10000);
}
