%CheckAnalyzers Unit tests for the SRS analyzers.
% This class, based on the matlab.unittest.TestCase framework, runs some simple
% tests on the analyzers in 'apps/analyzers'.
%
% CheckAnalyzers Properties (Constant):
%
% wd - Path of the directory containing this test.
%
% CheckAnalyzers Methods (TestClassSetup):
%
% testSetup - Common test setup.
%
% CheckAnalyzers Methods (Test, TestTags = {'matlab code'}):
%
% checkParserPUSCH - Checks that the parser for PUSCH logs.
% checkParserPUCCHF0 - Checks that the parser for PUCCH Format 0 logs.
% checkParserPUCCHF1 - Checks that the parser for PUCCH Format 1 logs.
% checkParserPUCCHF2 - Checks that the parser for PUCCH Format 2 logs.
% checkParserPUCCHF3 - Checks that the parser for PUCCH Format 3 logs.
% checkParserPUCCHF4 - Checks that the parser for PUCCH Format 4 logs.
