Example 1 with Configurator

use of org.lflang.tests.Configurators.Configurator in project lingua-franca by lf-lang.

the class TestBase method configure.

/**
 * Configure a test by applying the given configurator and return a
 * generator context. Also, if the given level is less than
 * `TestLevel.BUILD`, add a `no-compile` flag to the generator context. If
 * the configurator was not applied successfully, throw an AssertionError.
 *
 * @param test the test to configure.
 * @param configurator The configurator to apply to the test.
 * @param level The level of testing in which the generator context will be
 * used.
 * @return a generator context with a fresh resource, unaffected by any AST
 * transformation that may have occured in other tests.
 * @throws IOException if there is any file access problem
